Generators[]
Icon | Name | Description | Base Cost | Base Production | Requires |
---|---|---|---|---|---|
Mineral | The planet is composed of chemical compounds and elements. Earth's natural processes give these materials solid form, creating minerals. Almost all minerals are crystalline, with their atoms organized in orderly patterns. | 150 | 2/sec | Earthly Origins | |
Igneous Rock | As magma rises in the Earth's crust, it cools. When losing heat, it crystallizes, solidifying into igneous rock. | 50,000 | 1/sec | Magma | |
Sedimentary Rock | Nature is continuously breaking down rocks and organic material into smaller and smaller pieces. When weighed down by earth or other sediments, they can be compacted and recycled into new types of rock. | 1e7 | 250/sec | Sand | |
Metamorphic Rock | When descending deeper into the planet's crust and mantle, pressure and heat increase. These extreme conditions cause rock to undergo metamorphosis. | 3e8 | 100,000/sec | Igneous Rock Rock Cycle Sedimentary Rock Calcite | |
Crystal | Most minerals take shape as crystals formed by cooled, solidified magma. Their atoms are arranged in three dimensions, creating geometric shapes and flat surfaces at both the atomic and macro level. | 4e11 | 1/sec | Mineral Fluorite | |
Gem | Humans cut and polish crystals to enhance their aesthetic qualities. These gemstones are used in jewelry and signify wealth and power. | 3e12 | 1e8/sec | Crystal Diamond |

Miscellaneous Effects[]
Mineral Efficiency[]
Icon | Name | Description | Cost | Effect | Requires |
---|---|---|---|---|---|
Olivine | The oldest olivine crystals on Earth originate billions of years ago when meteorites crash into the planet. This mineral is also naturally occurring, believed to be the most common in the upper mantle. | 400 | 50% | Mineral | |
Quartz | The Earth's crust is comprised mostly of silicates, minerals containing oxygen and silicon. Quartz is among the most widespread of these minerals, present in nearly every type of rock. | 2,500 | 75% | Mineral | |
Feldspars | Making up 60% of the Earth's crust, feldspars are the most common silicates on the planet. A group of almost 20 different minerals, feldspars all share a crystalline structure that contains aluminum, oxygen, and silicon. | 7,800 | 50% | Mineral Quartz | |
Magma | A semi-liquid mixture of minerals, gases, and liquids flows within the Earth's mantle and crust. This molten rock is called magma and can reach extreme temperatures of up to 2,400 degrees Fahrenheit. | 32,000 | 100% | Quartz | |
Tuff | Formed from explosive volcanic eruptions, tuff is any rock made up of at least 75% volcanic ash. Tuff is softer and easier to cut than most other rocks, making it a useful construction material in ancient societies. | 18,000 | 125% | Igneous Rock Basalt | |
Clay | Constituting a fifth of the Earth's surface, clay is made of small and sticky minerals. Grains of clay clump together when wet and harden in high temperatures, allowing humans to mold them into tools and objects. | 900,000 | 75% | Mineral Basalt | |
Rock Cycle | Earth's processes from crystallization to weathering destroy, transform, and rebirth rocks throughout their many lifetimes. | 1.7e6 | 75% | Mineral Basalt | |
Sand | Weathering breaks down rocks exposed to the Earth's natural elements, such as water, wind, and sunlight. After thousands of years, exposed bedrock can be whittled down into the grains of sand that cover desert landscapes. | 4.5e6 | 150% | Rock Cycle | |
Sandstone | Often composed of sand-sized grains of quartz, sandstone makes up a quarter of all sedimentary rocks. If the rock contains a large amount of iron, it 'rusts' and turns orange after exposure to oxygen. | 2.5e8 | 125% | Sedimentary Rock Andesite | |
Calcite | A primary component of limestone, calcite is the mineral form of calcium carbonate. Its weak molecular structure makes it soft, easy to shape, and weak to acids such as vinegar. | 3e8 | 250% | Mineral Andesite | |
Granite | Composed of common minerals such as quartz and feldspar, granite forms as magma crystallizes deep within the crust. Over long spans of time, nature's elements can whittle down mountains, revealing their granite foundations. | 1e11 | 500% | Igneous Rock Scoria | |
Gneiss | When exposed to extreme pressures and temperatures above 570 degrees Fahrenheit, granite, shale, and sandstone can transform into gneiss. This rock contains a series of banded layers, each composed of different minerals. | 9e12 | 500% | Metamorphic Rock Shale | |
Fluorite | During the Mesozoic Era, the element fluorine mixes with the calcium in limestone, creating fluorite. Like many minerals, fluorite can form crystals, and it uniquely glows under ultra-violet light. | 7e10 | 1,000% | Mineral Shale | |
Pegmatite | When magma is allowed to crystallize slowly, massive crystals can form. Pegmatite is a rock composed of these giant crystals, which can grow up to 3 feet in length. | 5e14 | 10,000% | Igneous Rock Amethyst | |
Coal | Composed mostly of carbon, coal forms from prehistoric plant remains. It produces large amounts of energy when burned, making it the driving force of the Industrial Revolution. | 9e16 | 10,000% | Sedimentary Rock Topaz |
Igneous Rock Efficiency[]
Icon | Name | Description | Cost | Effect | Requires |
---|---|---|---|---|---|
Dunite | Intrusive igneous rock is created when magma crystallizes beneath the Earth's surface. Composed of minerals frequently found within the mantle, dunite most likely forms especially deep inside the planet. | 1,000 | 100% | Igneous Rock | |
Basalt | Magma from within the Earth's crust becomes lava when extruded to the surface. As this lava cools rapidly, it forms extrusive igneous rock. One such rock, basalt, makes up most of the ocean floor. | 5,000 | 100% | Igneous Rock | |
Andesite | Within steep-sided volcanos, andesite is formed from lava flowing above the surface. It is named after the Andes Mountains in South America, where the rock is common. | 3e7 | 3,000% | Igneous Rock Sedimentary Rock | |
Diorite | Beneath the Earth's surface, basalt and granite magma mixes, crystallizing into diorite. While the Mesopotamians use this stone for creating statues, today it can often be found in countertops and floors. | 3e7 | 3,000% | Igneous Rock Andesite | |
Scoria | Gassy magma ejected from a volcano experiences a rapid reduction in pressure, causing the gas to bubble. The holes on a scoria's surface are created when gas bubbles are trapped in the rock while it crystallizes. | 1e10 | 30,000% | Igneous Rock Metamorphic Rock | |
Obsidian | When lava cools rapidly on Earth's surface, it becomes obsidian, a type of volcanic glass. When fractured, obsidian forms extremely sharp edges that can cut human cells in half. | 6e16 | 3,500,000% | Igneous Rock Topaz |
Sedimentary Rock Efficiency[]
Icon | Name | Description | Cost | Effect | Requires |
---|---|---|---|---|---|
Limestone | Found in underwater or once-submerged environments, limestone forms as calcium-rich water sheds its minerals. Durable and versatile, it has long been used in construction, being employed in the building of the Egyptian pyramids. | 1e6 | 75% | Sedimentary Rock | |
Siltstone | Smaller than sand but larger than clay, silt is a sediment typically carried by water or wind. When these materials are deposited in environments like wetlands, the silt compacts into siltstone. | 6e6 | 100% | Sedimentary Rock | |
Coquina | As calcium carbonate is excreted from the shells of living creatures it becomes an adhesive, fusing the shells together to form a kind of limestone called coquina. | 3e11 | 10,000% | Sedimentary Rock Scoria | |
Shale | Found both above and in the ground, shale is a common sedimentary rock made up of clay, silt, and mud. Methane-based natural gas trapped in the pores of the rock can be used as fuel. | 9.5e11 | 20,000% | Sedimentary Rock Scoria | |
Chalk | Similar to coquina, chalk is a type of limestone that forms as minuscule shells are bound together by calcium carbonate. Deposits of chalk build up along the coast of England, creating the White Cliffs of Dover. | 1e14 | 4,000% | Sedimentary Rock Amethyst | |
Flint | Made of microscopic quartz crystals, flint is used for creating arrows and spear tips during the Stone Age. Striking flint with steel can scrape off pieces of the rock and heat them up, creating a spark that can start a fire. | 2e15 | 4,000% | Sedimentary Rock Amethyst | |
Natural Beauty | The untouched formations of rocks can be just as beautiful as carved jewels. Chinese artists of the 19th century create Gongshi, an art form based on presenting stones as representations of nature's pure beauty. | 2.5e21 | 100% | Sedimentary Rock Jade |
Metamorphic Rock Efficiency[]
Icon | Name | Description | Cost | Effect | Requires |
---|---|---|---|---|---|
Marble | High temperatures cause limestone minerals to grow and fuse, creating marble. The material is slightly harder than limestone, making it attractive to the Ancient Greeks for their sculptures. | 9e8 | 75% | Metamorphic Rock | |
Slate | Even relatively tame environmental conditions can produce metamorphic rock. Slate, for instance, is formed by low heat and pressure acting on shale and basalt. | 4e9 | 100% | Metamorphic Rock | |
Schist | Intense heat and pressure morphs shale into schist, a rock that tends to sparkle from an abundance of the mineral mica. It is common in New York City, and can be seen throughout Central Park and even mixed in the concrete sidewalks. | 5e12 | 20,000% | Metamorphic Rock Shale | |
Anthracite | Under extreme temperatures, coal can turn into anthracite. Characterized by high concentrations of carbon, it burns hotter and cleaner than any other variety of coal. | 1e17 | 1,500,000% | Metamorphic Rock Coal | |
Jade | Valued for its beauty and durability, East Asian cultures associate jade with both virtue and immortality from as early as the Han dynasty. It is an aristocratic symbol collected by the ruling class and used in burial rites. | 1.2e17 | 88,800% | Gem Lab-Grown Diamonds |
Crystal Efficiency[]
Icon | Name | Description | Cost | Effect | Requires |
---|---|---|---|---|---|
Amethyst | A variety of quartz, amethyst is formed when iron is present within the crystal. Exposure to heat and radiation causes a chemical reaction in the iron, giving the crystal its purple hue. | 8,000 | 100% | Crystal | |
Jasper | Sedimentary rock rich in silica can become jasper, whose crystals are too small to be seen by the human eye. The ancient Indus Valley civilization highly values green jasper, using it to carve other minerals and precious stones. | 500,000 | 500% | Crystal Amethyst | |
Fulgurite | If lightning strikes sand, it metamorphizes in an instant. The electricity heats up the sand, rapidly melting and crystalizing it into a shape that replicates the lightning's pathway. | 1.2e16 | 1,000% | Metamorphic Rock Jasper | |
Topaz | Naturally colorless, topaz is allochromatic, meaning it appears colored when other minerals interact with its crystal framework. Its structure is incredibly stable, allowing it to grow up to 600 pounds. | 4.5e7 | 2,000% | Crystal Jasper | |
Lapis Lazuli | Once among the world's most valuable stones, lapis lazuli is prized for its vivid blue color. The Badakhshan province in Afghanistan mines lapis lazuli for thousands of years, trading the crystal across much of the Ancient World. | 9e17 | 3,000% | Metamorphic Rock Coal | |
Diamond | When carbon is subjected to the pressures found deep in the Earth's crust, one of the hardest natural materials found on Earth is created. Diamond crystals have long been revered by humans and are incredibly valuable. | 1e11 | 4,000% | Crystal Coal | |
Pyrite | Known as 'fool's gold', pyrite's appearance mimics a more valuable mineral: gold. Despite its association with foolishness, the mineral is a leading source of sulfur, and prehistoric societies might have used it to produce fire. | 2.7e13 | 2,000% | Crystal Gem | |
Lab-Grown Diamonds | Grown from tiny slices of natural crystals or pieces of pure carbon, humans can produce artificial diamonds. While chemically and visually indistinguishable from those mined from the Earth, lab-grown diamonds are valued less. | 1.2e15 | 3,000% | Crystal Pyrite |

---|---|---|---|---|---|
Emerald | Most commonly found in pegmatite, the mineral beryl occurs in several colors. When mixed with chromium and vanadium beryl becomes green, and when it has been cut and polished, it is considered an emerald. | 3.3e12 | 150% | Gem | |
Aquamarine | Where green beryl is called emerald, bright blue beryl is known as aquamarine. Found primarily in Brazil, aquamarine is naturally blue and yellow but is typically exposed to heat by humans to achieve its iconic blue hue. | 6e12 | 150% | Gem | |
Opal | The brilliant colors of an opal come from spheres of water within the gem. This makes each stone fragile, so owners of opal are encouraged to touch it frequently, as the natural oils on their hands can protect it from damage. | 9e13 | 200% | Gem Pyrite | |
Garnet | The crystals of a garnet are typically twelve-sided and exist in six different colors. While red garnets are highly traded in Ancient Rome, green garnets are rarer and become the more valuable stone in later centuries. | 3e14 | 200% | Gem Pyrite | |
Sapphire | Corundum comes in a variety of colors, and with the exception of red, all are considered sapphire. The most beloved of these color variations is blue, a result of titanium mixing with the corundum during formation. | 3e15 | 500% | Gem Lab-Grown Diamonds | |
Ruby | When mixed with chromium, corundum becomes red. Ruby naturally has a dull, rough appearance. Humans cut and polish it into the radiant gemstone that serves as a symbol of passion and wealth. | 1.5e16 | 500% | Gem Lab-Grown Diamonds |
