英文摘要 | The petrology, mineral paragenese and microstructure suggest that the protoliths for the chenxing metabasite massif in tunchang area, hainan island probably are composed of gabbroic rocks ( coarse-grained amphibolites), gabbroic to diabasic rocks ( medium to fine-grained and medium to coarse-grained amphibolites) i and pillowed lava (fine-grained and/or massive amphibolites). these rocks are characterized not only by main mineral assemblages of amphiboles, plagioclase and chlorite which show at least two or more than two generations, but also by well-developed ductile-brittle shear deformations, being related to regional/thermal metamorphism and/or sea-floor metamorphism. the mineral chemistry of zoned amphiboles in the metabasites indicates a progressive evolution at early stage, being consistent with increasing ti, al and (k+na) from core to rim. by contrary, the reverse trend for ti, at and k+na contents reflects another retrogressive evolution. the whole rock and amphibole separate yield a sm-nd isochronic age of 128 +/- 12 ma, whereas the rb-sr whole-rock ages are 131.8 +/- 6.2 ma and 344 +/- 11 ma, respectively. |
