长期以来,国内外许多学者,对含金刚石的原岩金伯利岩及其矿床,进行了卓有成效的研究,取得极为丰硕的成果.过去一直认为,原生金刚石矿床仅产于金伯利岩中,但随着地质研究工作的不断深入,国内外均已证实钾镁煌斑岩(金云火山岩)及超基性岩中亦含有原生金刚石.近年来在新疆塔里木地台的南部(和田)及其西北边缘相继发现了金刚石砂矿及原生矿的线索,这证明在塔里木地台区有蕴藏金刚石矿床的可能性,为在巴州地区寻找金刚石矿床坚定了信心.
For a long time, many scholars at home and abroad have carried out fruitful research on original diamond-bearing kimberlites and their deposits, and have achieved extremely fruitful results.It has been thought that primary diamond deposits are only produced in kimberlite, but with geological Research has been deepened both at home and abroad have confirmed that porphyrite (Jinyun volcanic rocks) and ultramafic rocks also contain primary diamond.In recent years in the southern Tarim Taiwan (Wada) and its northwestern edge have been found The clues to diamond sands and primary mines confirm the possibility of depositing diamond deposits in the Tarim Basin area and give confidence in finding diamond deposits in the Bazhou area.
