| Geochemical Characteristics of the Plagiogranites in the Vicinity of Bingdaban,Central Tianshan |
| |
| 摘 要： | The tectonic and geochemical characteristics suggest that the plagiogranites exposed in the vicinity of Bingdaban on the northen margin of the central Tianshan uplift zone show a distinct mantle-source character, and their enrichment in LREE and selected enrichment in LILE(large ion lithophile elements)reflect a setting related to an arc tectonic regime.These rocks represent the products formed at shallow levels from mantle-derived magmas modified with subduction components(or super crustal rocks).

| Abstract: | The tectonic and geochemical characteristics suggest that the plagiogranites exposed in the vicinity of Bingdaban on the northern
margin of the central Tianshan uplift zone show a distinct mantle-source character, and their enrichment in LREE and selected
enrichment in LILE (large ion lithophile elements) reflect a setting related to an arc tectonic regime. These rocks represent
the products formed at shallow levels from mantle-derived magmas modified with subduction components (or super crustal rocks).
