A new report of the early Palaeozoic hornblendite in South China and its tectonic significance

Outcrops of early Palaeozoic mafic rocks are limited in the South China Block (SCB), which become a barrier to unlock the related tectonic evolutionary history. We present a new report of early Palaeozoic Pengxi hornblendite at Xiajiang County, Jiangxi Province, in this paper. The Pengxi hornblendite has a concordant zircon U–Pb age of 433 ± 2 Ma (40 grains) which could represent its formation time. It is characterized by high MgO content...
