Ever wonder how Earth scientists examine rocks? We cut them up and throw them under a microscope ... and then everything ...

A typical Martian rock is similar to the diabase rocks from Rydaholm, Sweden, due to their evenly sized plagioclase and orthopyroxene grains. In the lab, Katayama and Akamatsu measured P-wave and ...

Hole SN-25-02 intersected 14.00m grading 1.04 g/t PGEs with 0.19% Cu, including 1.86m grading 2.55 g/t PGEs with 0.46% C. Drilling to date indicates a large Midcontinental Rift-style intrusion, ...

Rising 235 feet from the surf at Cannon Beach, Haystack Rock is Oregon’s most photographed chunk of coastline for good reason ...

These formations occur in succession within the same drilling profile. The minerals constituting garnet bearing amphibolite include amphibole, garnet, plagioclase, kaolinite, and opaque minerals.

The feldspar is An 70 labradorite, a high calcic plagioclase; the aventurescence-causing inclusions have been identified as pure native copper. Microprobe analyses conducted on colorless, red, and ...

U-Pb accessory phase geochronology Trace element analysis of major silicate phases (garnet/olivine/pyroxene/plagioclase/mica) Trace element analysis of accessory ...

Since Ca-plagioclase (anorthite) is a major component of the substrate and dissolves quickly under these geochemical conditions, kaolinite and montmorillonite are the most abundant clay minerals ...
