中甸洛吉地区的超基性岩属于甘孜—理塘洋脊型火山岩—蛇绿岩带的南延部位,甘孜—理塘蛇绿岩带在空间上沿玉树、玉隆、甘孜、理塘、木里—带展布,在西邓柯—玉树间与金沙江蛇绿岩带相接。自木里向南岩带延伸不清楚,在木里、三江口、中甸、土官村—线断续出露。整个岩带围限于甘孜—理塘断裂带内,以断层为界,西邻义敦火山岛弧,东接巴颜喀喇—雅江冒地槽褶皱带。洛吉地区的超基性岩主要分布于二叠系木星土组和三叠系坪子组中。坪子组中超基性岩与木星土
The ultrabasic rocks in the Zhongdian Luoyang area belong to the southern extension of the Garze-Litang ridge-type volcanic-ophiolite belt. The Ganzi-Litang ophiolite belt spatially runs along Yushu, Yuluo, Ganzi, Litang , Muli - belt distribution, in the West Dunko - Eucalyptus and Jinsha River ophiolite phase. Since the wood to the south rock belt extension is not clear, in Muli, Sanjiangkou, Zhongdian, Tu official village - line intermittent exposure. The entire rock zone is confined within the Ganzi-Litang fault zone, with faults as the boundary, the Yidun volcanic island arc to the west and the Bayanqala-Yajiang pelagic trough fold belt to the east. The ultrabasic rocks in the Loi Ji area are mainly distributed in the Permian Juxingtu Formation and Triassic Pingzi Formation. Pingzi Formation Ultramafic rocks and Jupiter soil
