Genesis of a giant Paleoproterozoic strata-bound magnesite deposit: Constraints from Mg isotopes
Dong, Aiguo; Zhu, Xiang-kun; Li, Shi-Zhen; Kendall, Brian; Wang, Yue; Gao, Zhaofu (Elsevier, 2016-08-01)Giant strata-bound magnesite deposits are absent in modern and most Phanerozoic sedimentary environments but occur predominantly in Precambrian strata. These deposits may have formed directly through precipitation of evolved ... -
A multi-isotope approach towards constraining the origin of large-scale Paleoproterozoic B-(Fe) mineralization in NE China
Dong, Aiguo; Zhu, Xiang-kun; Li, Zhihong; Kendall, Brian; Li, Shi-Zhen; Wang, Yue; Tang, Chao (Elsevier, 2017-05-01)Borate ore deposits occur predominantly in Phanerozoic evaporative sedimentary environments but are scarce in Precambrian strata. However, massive B- and Mg-rich borate deposits are abundant in the Paleoproterozoic strata ...
