摘要
沿浙江诸暨石角、陈察分布的前寒武纪超基性岩分别为绍兴一江山对接带古洋壳下覆含水地促残留作和华夏古地体原始地侵高温底辟侵入体。两地超基性岩结构构造的独特性，与所处古地质构造单元之间推覆超法的运动学性质有关。岩体在地质特征和宕石化学、矿物化学等的明显差异，以及由此引致的特殊的成因条件，是分划两个不同古地质构造单元的依据：石角、陈蔡超基性岩体，应分别属于不同威尔逊旋回，同一俯冲阶段的前寒武纪上地幔深部成因的侵入岩。
Precanbrian ultrabasic rock, which was distributed along Zhuji Shijio and Chen Cai in Zhejiang, is the remainder of watering earth mantle under paleocean shell for Shaoxing - Jiangshan suture zone and the intrusive rock derived from hot diapir strcture of Huaxia old original mantle. There was some relationship between the unique texture structure of ultrabasic rock and the dynamic nappe structure of old geological characteristics. The identification of these two old geology tectonic units is based on the apparent difference of geological characteristics, rock chemistry, mineral chemistry for rocks as well as the special consequent conditions. The ultrabasic rock of shijio and Chen Cai could be attributed to the deep earth mantle reslted from different Wilson cycles but the same a dive part of Precambrian period.
