内容記述(抄録等)
In a previous paper (Kitahara, 1957), the writer described the outlines of his studies on the chromites and their country rocks in the Tari distrct, Tottori Prefecture.
In another previous paper (Kitahara, 1958), the writer dealt principally with the results of his studies on the chromites, including the description of leucocratic differential rocks in the region.
In the present paper the writer wishes mainly to describe his studies on the differential dykes generated from peridotitic magma containing chromic oxide and a few minerals formed by metamorphic or metasomatic replacement in the country rocks of the chromite deposits in the said region.
The origin of chromite deposits in the same region is also mentioned briefly in this paper.
