J.P.Albe rs进行了一项研究,致力于发展一种地质一地球物理技术,以探测加里福尼亚州德尔诺特县乔斯芬超镁铁质岩体中的隐伏豆夹状铬铁矿床、锡斯基尤县北部浸染状铬铁矿床,以及美国西科迪勒拉发育这种类型大矿床的可能产地.另外一个目标是评价发育在超镁铁质岩石上的含镍红土的远景. 地质结果表明,在德尔诺特县Low Plateau地区,豆荚状铬铁矿沿橄榄岩叶理走向断续产出.然而,对任何单个铬铁矿的产状的地质控制因素仍旧是不清楚的,并非铬铁矿总是产于纯橄岩中.这说明叶理走向是原生构造,可能是在超镁铁质岩结晶时,而不是在后来的变 JPAlbe rs conducted a study devoted to the development of a geophysical-geophysical technique to detect bed of hidden legume-like chromite in the Josfenen ultramafite in Delnot County, California, An exuded chromite deposit in the north of Skiyou County and a possible site for the development of this type of large deposit in the US West Cordillera Another goal is to evaluate the future of nickeliferous laterites developed on ultramafic rocks. The results show that in the Low Plateau region of Delnot county, pod-like chromites progress intermittently along the foliaceous foliage.However, the geological control of the occurrence of any single chromite remains unclear, not The chromite is always produced in dunite, which shows that the foliage is migrated to the original structure, probably during the crystallization of ultramafic rocks rather than later
