Nature of the Skarn–Borosilicate Deposit Giants of the Sikhote-Alin and Pamir Mountains

It is shown that the giant Sikhote-Alin and Pamir deposits of boron are associated with fragments of the boron-bearing evaporite strata of paleoceanic atolls in the subduction mélange. Ore formation relates both to in situ transformation of boron-bearing evaporite strata at the Ak-Arkhar deposit and...

Description
Summary:It is shown that the giant Sikhote-Alin and Pamir deposits of boron are associated with fragments of the boron-bearing evaporite strata of paleoceanic atolls in the subduction mélange. Ore formation relates both to in situ transformation of boron-bearing evaporite strata at the Ak-Arkhar deposit and to boron mobilization and redeposition some distance away from the evaporite source in course of intensive post-accretionary fluid-magmatic reworking of the subduction mélange at the Dalnegorskoe deposit.
