It is difficult to conform the derivations of the native heavy minerals, so the author assumes corresponding procedures as follows to accomplish the research task : firstly, according to the composition typomorphic peculiarities of minerals deriving from mantle, the author selected a part of minerals as preliminary reseach objects from the native heavy minerals and then further investigate the mantle ones and their host rocks in two ways : one is the method of comparation with the corresponding minerals of rocks deriving mantle in the research field and other places ; anorther is the method of multivariate statistical analysis
本次工作為了盡可能地排除非幔源礦物的干擾，根據陳光遠（ 1990 ） 、潘兆櫓（ 1994 ）等學者有關礦物成分標型的論斷，篩選出地幔特徵元素含量較高的重砂礦物做為初步研究對象，為達到研究目的採取了如下方法：與區內已發現的幔源巖石（如鉀鎂煌斑巖等） 、國內外有代表性的堿性玄武巖、金伯利巖、鉀鎂煌斑巖的深源包體中的相應礦物進行對比研究的方法；多元統計分類的方法。Because of the absence of mantle xenoliths and xenocrysts, it is the first time that this paper looks on the native heavy minerals deriving from mantle, which were collected at the terraces of the two rivers, kalakshi river and yulongkashi river, as objects and takes into account the geochemical characteristics of the rocks deriving from mantle such as keliyang lamproite and so on to study the composition of lithospheric mantle, the characterics of palaeozoic era lithospheric mantle, mantle thermal state, and diamond metallogentic mantle geological conditions in research field
為達到研究目的，本文首次以喀拉喀什河和玉龍喀什河沿岸階地的幔源重砂礦物（單斜輝石、鉻尖晶石類礦物、鈦鐵礦以及石榴石）為研究對象，結合鉀鎂煌斑巖等區內已發現的幔源巖石及其中地幔物質對該區地幔物質的組成、古生代巖石圈地幔特徵、巖石圈熱狀態以及該區金剛石成礦地幔地質條件做了嘗試性的研究工作。
