Bentonite is an absorbent swelling clay containing montmorillonite. Forms from volcanic ash weathering in seawater or hydrothermal circulation. Contains up to 40-50% amorphous silica dissolved during alteration. First discovered in Cretaceous Benton Shale near Wyoming
Alabaster is a soft mineral used for carving and plaster production. Two main types: fine-grained gypsum and banded calcite. Gypsum alabaster is soft (Mohs 1.5-2), calcite harder (Mohs 3). Both types are translucent and slightly soluble in water
Serpentinite forms from mafic rocks through serpentinization by sea water. Main minerals include antigorite, lizardite, chrysotile, and magnetite. Forms at mid-ocean ridges and subduction zone forearc mantles
Silicates are polyatomic anions containing silicon and oxygen. Silicon forms tetrahedron with four oxygen atoms connected by covalent bonds. Oxygen atoms link to other cations (Mn+) in strong Si-O-M-O-Si linkage
Ochre is a natural yellow mineral pigment made of iron oxyhydroxide. Contains minimum 12% iron oxyhydroxide, ranging up to 30%. Composed of clay, siliceous materials, and hydrated iron oxide limonite
Mines located in north Mountains, accessible after Spring 5th. Contains 120 floors divided into three thematic sections. Players can mine rocks with Pickaxe and collect minerals with Hoe. Ladders appear after breaking rocks or defeating enemies
