【摘要】 <正> 一、引言 作者曾研究东海海域长江口以东和济州岛西南海底沉积物样品中一元和二元脂肪酸的分布特征,其结果表明,一元脂肪酸碳数分布的最高峰在mo-C_16:0,其物质来源是原地水生的海藻腐烂物质,二元脂肪酸碳数分布的最高峰在di-C₂₄或di-C₂₈其物质来源是陆源高等植物碎屑。作者还报道了位于陆架海与琉球群岛之间的冲绳海槽沉积物中细菌标志物——不饱和脂肪酸的分布特征,研究结果表明,不饱和脂肪酸在沉积物中的含量更多还原

【Abstract】 This paper deals with monoterpinenese in Okinawa Trough sediments, which have been identified by TLC and GC-MS-DS. Three kinds of monoterpinene have been recognized: cyclohexene, 1-methyl-3-( 1-methylethenyl), cyclohexene, l-methylethenyl-5-( 1-methylethenyl) and cyclohexene,1-methyl-4-(1-methylethylidene). These monoterpinenes are considered to have been derived from terrigenous higher plant detritus and are recognized as a new type of terrigenous markers.更多还原
