The study focuses on the  comparison of the chemical and mineral composition of Lunar regolith probes from Luna-16, -20, -24 stations and their the sea-continent environments. Using microprobe JXA-8200 and JSM-5610LV (400 analyses, 50 images, 9 fragments of layer-by-layer core samples) 18 mineral phases and their 12 varieties were diagnosed. The most common are iron-magnesium and calcium-bearing varieties of silicates – anortite, clinopyroxenes and olivine. The typomorphic features of rock-forming minerals in two types of the lunar surface are discussed. The composition of chromespinelids is demonstrated on a triangular prism diagram.
