The concept of metallogenic province has won general acceptance in economic geology. It is agreed that metallogenic provinces offer good opportunities for exploration of new ore deposits. The concept of geochemical province is also established, but i

The mercury ores of the New Idria Mining District are composed of metacinnabar and cinnabar with minor amounts of stibnite and iron disulfides. Metacinnabar from the main ore zone at the New Idria Mine contains Fe as a major impurity (0.96 to 2.80 wt

Pampa del Infierno, an L6 chondrite, displays strong evidence of impact metamorphism. Rare chondrules and two types of dark-colored clasts occur in a light-colored matrix. Granular clasts are similar in mineralogy and chemistry to the host meteorite,

A proton induced X-ray emission (PIXE) method has been developed for determination of the concentrations of elements (with Z > 12) in geological samples. In this procedure proton bombardment is utilized to induce characteristic X-rays in all elements
