Since I am attending College of the Siskiyous in Siskiyou county, I took the liberty of asking the geology professor if he knew anything about 'The Rock'. He informed me it could be sent to the University in Santa Barbara to have it x-rayed to see what is on the inside. For starters, the professor did help me in doing some of the ground work to find what kind of rock or mineral family it may come from. Carbonate Minerals Carbonates are compounds in which one or more metallic or semimetallic elements combine. These minerals are found in Limestone and Marble quarries.
Limestones usually come from shells or ancient sea animals.
Marble is metamorphized from heat or pressure. The first procedure was to see what possible mineral it may be. To test for this, a drop of cold diluted hydrochorlic acid was dropped onto the rock, and if it effervesis it means it is a carbonate mineral. The quest continued - A specific gravity test was done. The specific gravity is 2.71.
