岩体分为 A、B、C 三个大的韵律旋回,五个岩相带。应变矿物主要见于 B 韵律旋回的下部 B_1岩相带中。下部 A 岩相带由橄榄辉长岩和含钒钛磁铁矿的橄榄岩、橄长岩组成,二者呈厚度不等的层状相间出现。辉长岩具辉长结构,块状构造。中部 B 韵律旋回可分为 B_1(下部)和 B_2两个岩相带。B_1岩相带由橄榄辉长岩和含矿橄榄岩、橄辉岩组成,其中含矿橄榄岩、橄辉岩主要分布于 B_1岩相带的下部,形成厚大的流层状矿体,向上则呈较薄的层状夹于辉长岩中,
Rock mass is divided into A, B, C three large rhythm cycle, five lithofacies belt. Strain minerals are mainly found in the lower B-1 lithofacies of the B-prosody cycle. The lower A lithofacies consist of olive gabbros and peridotites and olivines containing vanadium-bearing titanomagnetite, with thick layers ranging in thickness from each other. Gabbro with glitter structure, block structure. Central B rhythm cycle can be divided into B_1 (lower) and B_2 lithofacies. B_1 lithofacies consists of gabbro and ore-bearing peridotites and olivines. The ore-bearing peridotites and olivines are mainly distributed in the lower part of B_1 lithofacies to form thick stratoid orebodies, It is thinner layered sandstone in the gabbro,
