Meteorites that produce K-feldspar-rich ejecta blankets ...

Meteorite impacts load the atmosphere with dust and cover the Earth's surface with debris. They have long been debated as a trigger of mass extinctions throughout Earth history. Impact winters generally last <10 years, whereas ejecta blankets persist for 103–105 years. We show that only meteorite impacts that emplaced ejecta blankets rich in K-feldspar …

Feldspar Distinctions, Characteristics & Identification

Orthoclase, or orthoclase feldspar (endmember formula KAlSi 3 O 8 ), is an important tectosilicate mineral which forms igneous rock. The name is from the Ancient Greek for "straight fracture," because its two cleavage planes are at right angles to each other. It is a type of potassium feldspar, also known as K-feldspar.

Feldspars - all about the plagioclases and K-feldspars

The chemical composition of feldspars includes alcalic metals, aluminum, silica and oxygen. The general chemical formula is a bit complicated (K,Na) 1-x (Ca,Ba) x (Si 3-x Al 1+x O 8).This complexity is caused by presence of both monovalent and divalent cations which require more complicated heterovalent substitution.

Feldspars are generally light colored minerals, white or buff to gray in color. One species, microcline, may also be light brick-red or even the green to blue green variety called amazonite. Because their atomic framework has planes of weakness, feldspars exhibit good cleavage, breaking readily into blocky pieces with smooth sides.
