| Abstract: | The heavy mineral content data of 235 bottom-surface sediment samples collected from the East China Sea were subjected to statistical analysis by means of the Q-model and R-model. As a result of the Q-model analysis, the area investigated may be divided into 3 mineral provinces: A--the Okinawa Trough mineral province of pyroxene and magnetite;B-the western mineral province of mica, chlorite and dolomite; C-the mouth of the Changjiang River and the middle mineral province of hornblende and epidote.
On the other hand, the results of the R-model analysis indicated that the 10 heavy minerals of the area investigated may be divided into 3 mineral groups: A-pyroxene and magnetite; B-mica, chlorite and dolomite; C-hornblende, epidote,granet, ilmenite, staurolite etc. These three mineral groups are similar to the characteristic mineral assemblages of the A, B and C end-members produced by Q-model analysis, respectively.
The results of this paper are similar to those obtained in the former paper1] using characteristic minerals as a basis for delineation of mineral provinces. |
