The most Li deposits were found in lake waters or igneous rock. In recent years, anomalous concentrations of lithium in coal have been reported by several coal geologists （Sun et al., 2010, 2012a, 2013a; Dai et al., 2012）. Some coal geologists argued that these concentrations have economic significance （Sun et al., 2012b, 2013b, 2014）. This discovery has even been reported by Khanchuk et al. （2013） in ＂The Newsletter of Society for Organic Petrology＂, and the report was reprinted by the Geospectrum of the American Geosciences Institute （Geospectrum, 2014）.

对南黄海中部泥质区的三个柱样(ZY-1,ZY-2和ZY-3孔)进行了AMS14C测年、沉积层序以及沉积物敏感粒级的分析.结果表明此三孔的岩性上下均一且沉积连续,均为黏土质粉沙,是全新世高海平面以来的沉积产物.ZY-1,ZY-2和ZY-3孔的粒度垂向变化特征基本一致,主要受控于现代黄海环流体系中冬季风驱动的黄海近岸海流的强弱,间接反映了东亚冬季风强弱变化.利用ZY-1,ZY-2和ZY-3孔的沉积物敏感粒级获得了近7200年来高分辨率的东亚冬季风替代指标,发现在7.2～4.2ka期间东亚冬季风强盛且波动大,4.2～1.8ka期间东亚冬季风表现为中等强度且比较稳定,东亚冬季风强度在1.8～0ka期间虽较弱,但在此阶段后期略有上升.中全新世以来,南黄海中部泥质区所记录的东亚冬季风变化趋势在千年尺度上与已报道的东亚夏季风强度变化趋势基本一致,主要受控于轨道驱动的太阳辐射量冬、夏季季节性变化差异;但在百年尺度上东亚冬季风增强事件则与夏季风减弱事件相对应,呈现反向变化,可能是对太阳活动减弱的敏感响应.
