Laterite (Pedology 🟤)

Laterite is a soil type rich in iron and aluminum that often forms in hot, wet areas; most such soil is found in the tropics. Nearly all laterites are of rusty-red coloration due to high iron oxide content. Laterite soils develop by intensive and prolonged weathering of the underlying parent rock, usually under conditions of high temperatures and heavy rainfall...

Mineral Monday: Diatoms Diminish Dolomite By Huifang Xu Laboratory syntheses results demonstrate that the dissolved silica can catalyze dolomite precipitation. More diatoms = Less dolomite. #MSACommunications #MineralMonday #dolomite #diatoms #sedimentology #chemicalweathering

Desert varnish (Deserts 🏜️)

Desert varnish or rock varnish is an orange-yellow to black coating found on exposed rock surfaces in arid environments. Desert varnish is approximately one micrometer thick and exhibits nanometer-scale layering. Rock rust and desert patina are other terms which are also used for the condition, but less often.
