A small (0.4 km2), unexposed, ankeritic-sideritic carbonatite intrusion. Its mineralogy is dominated by alternating bands of ankerite and siderite with interstitial chlorite and synchisite-bastnaesite. Minor phases include apatite-rich carbonatite veins; narrow zones (dykes) of intense chloritization; biotite silico-carbonatite and orthoclase-dolomite carbonatite.
