Commercial Quarry Crestmore CaliforniaEverything You Need to Know About Sandstone

CRESTMORE ROCKS General Description There are exposed at Crestmore crystalline limestone and other metamorphosed sediments enveloped in and cut by intrusive igneous rocks The limestone is coarsely crystalline with calcite grains usually 3 or 4 mm and occasionally 15 to 30 mm in diameterJan 26 32 Sandstone simply put is sand cemented together into rock — this is easy to tell just by looking closely at a specimen But beyond that simple definition lies an interesting makeup of sediment matrix and cement that can with investigation reveal a great deal of valuable geologic information

This rock shall serve as an example for an intrusive igneous rock as opposed to volcanic igneous rocks that is incompatible with quartz The rock is coarse grained just as a granite but much darker with a conspicuous greenish colorThese rocks usually have a coarse texture individual minerals are visible without magnification because the magma cools slowly underground allowing crystal growth Common rock types within the intrusive category are granite and diorite Granite Granite is the intrusive equivalent of rhyolite but has a coarser texture A 12 square mile
