The coloring agent in this sand is volumetrically insignificant - it is hematite (oxide of iron) that forms very thin rust-colored pigment on larger silicate grains.Gold production from the northern Pataz district in the eastern Andean Cordillera of Peru has been sourced mainly from mesothermal quartz-carbonate-sulfide veins hosted by the Mississippian Pataz batholith.
Petrified wood has long held a fascination for people from all over the world. Petrified wood in Oklahoma is no exception. In Oklahoma, petrified wood occurs in two basic forms. First, as pebbles or cobbles in river gravels. Second, it has been found in place within the rock formation in which it was originally formed.ABSTRACT Understanding petrographical, geochemical and electrical properties of rocks is essential for investigating minerals.
