The results of high temperature and high pressure experimental research indicate that the occurrence of deep-focus earthquakes is closely related to the mantle phase transformation .

该区原始地幔矿物成分为橄榄石（728%）、单斜辉石（124%）和石榴石（148%），属含单辉石榴橄榄岩的地幔。

The local primordial mantle consists mainly of olivine ( 72 8 % ), clinopyroxene ( 12 4 % ) and garnet ( 14 8 % ), and is a clinopyroxene bearing garnet peridotite mantle .

根据各类玄武岩水含量推断出的上地幔源区的水含量，和由地幔岩主要矿物&橄榄石的水含量估算出的上地幔水含量（质量分数）很接近，在0.02%左右。

The water content of the upper mantle as inferred from the water content of basalt is 0.02 % . This is consistent with the value estimated from olivine in mantle 's xenoliths .
