The article describes a data on the chemical composition of the lunar soil in the area of PKT (Procellarum KREEP Terrane). This area encompasses the main part of the "marea" basaltic volcanism of the visible side of the Moon. KREEP in the name of Procellarum KREEP Terrane title (PKT) means potassium (K), rare earth elements (REE) and phosphorus (P). In the area of PKT according to the data of Lunar Prospector it is observed an elevated contents of thorium, that is a sign of the presence of KREEP- rocks. The area of PKT is located on the visible hemisphere of the Moon. The chemical composition of the surface layer of the Moon in the area of PKT was determined by a gamma spectrometer of the spacecraft Lunar Prospector in 1998.
