重力分异,重力弥散;
Compared with the gravitative differentiation and lateral-stress effects, the thermodynamic action is considered as primary driving force, and the others are secondary.
热动力作用是主驱动力,沉积物差异重力和水平应力作用是次驱动力。
The first intrusive phase which constitutes the main part of the complexes is best differentiated and has a differentiation trend, due to gravitative crystallization differentiation, from peridotite facies and olivine-gabbro, facies to quartz-bearing norite-gabbro facies with basicity decreasing successively.
第一侵入期构成岩体的主体部分,分异良好,由重力结晶分异形成自橄揽岩相、橄榄辉长岩相向含石英苏长辉长岩相的分异趋势,基性程度依次降低。
