英文摘要	The Huguangyan Maar Lake (HML) (21°9'N, 110°17' E), situated on the Leizhou Peninsula in the southernmost of mainland China, is the deepest recent crater lake among the identified volcanic structures in the Leiqiong Volcanic Field. The bi-lobate lake, with a diameter of ? 1.7 km and a depth of ? 20 m, is surrounded by a high tephra wall and is underlain by a basalt sheet. K/Ar dating on basalts from the volcanoclastic breccia of the crater rim yielded an age of ca. 127 ka. Climatically, the HML lies in the transition zone between southern subtropical zone and tropical north, and is influenced by both the East Asian summer and winter monsoons. A recent study by Yancheva et al. (2007) has shown that the HML sediments record plentiful paleoclimatic and paleoenvironmental details since the Late Pleistocene. However, the sediment sources of HML have become a matter of intense debate since Yancheva et al. (2007) proposed that wind-blown material transported by the East Asian winter monsoon from arid North China is the main lithogenic sources to the HML sediments. In order to better understand the provenance of the HML sediments, which is a prerequisite for comprehensively assessing the reliability of various paleoclimatic and paleoenvironmental proxies, we carried out a combined rock magnetic and geochemical analyses of both the HML sediments and local pyroclastic rocks surrounding the lake.
