Question

The geologic laboratory where you work received a sample for analysis that is composed of calcite that includes many microscopic fossils of marine organisms and reacts with acid. what name would identify this rock?

Answer 1

The rock described is limestone, which is composed of calcite and contains microscopic fossils of marine organisms.

Step-by-step explanation:

The rock that you have described, composed of calcite with microscopic fossils of marine organisms and reacting with acid, is called limestone. Limestone is a sedimentary rock that is primarily made up of calcite, which is a mineral form of calcium carbonate. It commonly contains fossils of marine organisms, such as shells and microscopic organisms.

Answer 2

The name that would identify the rock is aragonite. This rock is composed of calcium carbonate or calcite and is produced by the fossils of marine organisms. This rock is highly basic due to its composition and reacts strongly with acids.
