dc.description.abstract	The Dambukin block of the Stanovoi terrane encloses abundant small (up to 5 km2) massifs, dikes, and sills composed of the cortlandite–pyroxenite–gabbro association. Previously, they were arbitrarily considered as Early Archean and Early Proterozoic formations. The dikes and sills are 1–2 km long and a few dozen meters thick. The association is largely represented by mesocratic and melanocratic gabbro, hornblendites, pyroxenites, cortlandites (hornblende peridotites), and less common dunites. In addition, phlogopite and pargasite (hornblende) are characteristic of cortlandites, while brownish green hornblende is typical of gabbroids.
