All three produce labradorite feldspar ranging from near-colorless to pale yellow ... (1966), the sunstone lavas within the Rabbit Basin are petrographically similar to plagioclase-rich flows within ...

Two types of feldspar were detected: K-feldspar (microcline) and Ca-Na plagioclase (labradorite-anorthite). Most of the feldspar inclusions were twinned, measuring approximately 300 to 400 µm. Their ...

In a study co-authored by a Texas A&M University scientist, researchers have revealed new insights into the geological ...

A team of scientists has uncovered new details about Mars’ Jezero Crater using the Perseverance rover's cutting-edge ...

NASA's Perseverance rover has revealed new clues about Mars' volcanic past. While most people searching for signs of alien life these days might have their eyes on the exoplanet K2-18b, one team ...

Feldspar successfully completes the first functional prototype of its sensor-enabled, high-performance track, marking a historic leap in sports flooring technology. Early testing with some of the ...

The first type, dark-toned and rich in iron and magnesium, contains intergrown minerals such as pyroxene and plagioclase feldspar, with evidence of altered olivine. The second type, a lighter ...

"albite” is a plagioclase feldspar mineral "aplite” An intrusive igneous rock in which the mineral composition is the same as granite, but in which the grains are much finer "argillic alteration” is ...

But from the closeup image, a reasonable guess is that the white parts of the rock are feldspar, a common mineral in both Earth’s and Mars’ crust. The black stripes could be a pyroxene ...
