Detrital zircon U–Pb ages of the Proterozoic metaclastic-sedimentary rocks in Hainan Province of South China: New constraints on the depositional time, source area, and tectonic setting of the Shilu Fe–Co–Cu ore district

Provenance and depositional setting of Lower Silurian siliciclastic rocks on Hainan Island, South China: Implications for a passive margin environment of South China in Gondwana

“…1.8-1.45 Ga volcano-clastic sediments of the Baoban Group interpreted to have been deposited in a rifted back-arc basin (Xu et al, 2001a). The late Mesoproterozoic to early Neoproterozoic Grenvillian orogeny, which led to the amalgamation of the Yangtze and Cathaysia Blocks to form the united South China as part of Rodinia (Li et al, 2002a(Li et al, , 2008a, is also probably recorded by detrital zircons in the metamorphic sedimentary rocks from the late Mesoproterozoic-Neoproterozoic Shilu Group and overlying Shihuiding Formation (Wang et al, 2015a) as well as from the Ordovician to Silurian strata on Hainan Island.…”

Geochemical and Nd isotopic constraints on provenance and depositional setting of the Shihuiding Formation in the Shilu Fe–Co–Cu ore district, Hainan Province, South China

“…The Shihuiding Formation is one of three Precambrian sequences on the island, with the other two being the Paleo-to Mesoproterozoic Baoban Group and the late Mesoproterozoic to early Neoproterozoic Shilu Group (Zhang et al, 1990;Wang et al, 1991bWang et al, , 2015Li et al, 2002aLi et al, , 2008aXu et al, 2015). Among these three sequences, most attention has been paid to the Baoban Group and Shilu Group, partly because of the economic significance of their Au and Fe-CoCu ores, respectively (Xu et al, 2013(Xu et al, , 2014.…”

In contrast, relatively little is known about the Shihuiding Formation, and the scant research that exists has focused on the geochronology (Zhang et al, 1992;Li et al, 2008a;Wang et al, 2015) and lithology (Wang et al, 1991b;Yao et al, 1999) of the formation. This lack of information has led to a tentative genetic link being proposed between the Shihuiding Formation and the Shilu Fe-Co-Cu district (for a comprehensive review, see Wang et al, 2015).…”

The Precambrian tectonic evolution of Hainan Island has been the subject of much debate in terms of its paleontology (Zhang et al, 1990), petrology (Xu et al, 2001a), stratigraphy, structural geology (Wang et al, 1991a(Wang et al, , 1991bZhang et al, 1997), and geochronology (Li et al, 2008a(Li et al, , 2012Wang et al, 2015;Xu et al, 2015).…”

The Shihuiding Formation definitely constitutes an integral part of the Precambrian geologic history of Hainan Island.…”
