Accordingly, their refractory element contents are higher than those of the Australiasian tektites. Only one out of the 9 spherules of the ODP 1144 microtektites exhibits low Al2O3 abundance, 13.0%. Also, the contents and some ratios of the refractory elements of this spherule differ much from the other ODP 1144 microtektites, but similar to those of the tektites from Zhanjiang and Wuchun.

从成分上看，这些微玻璃陨石存在两种不同的类型，其中的绝大部分Al2O3含量在19.0%以上，属于高Al类型，相应的难熔微量元素含量也比较高；个别微玻璃陨石Al2O3含量(13.0%)和难熔微量元素含量较低，微量元素含量和特征比值都与邻近的广东省湛江和吴川的玻璃陨石相近。

Conversely,the content of crude fiber,dry matter and nitrogen-free extract were high in setting stage although the content trends aneurolepidium dasystachys has a little different.

其中赖草的干物质、蛋白质、粗脂肪、无氮浸出物和粗灰分含量显著高于川草ⅰ号、川草ⅱ号、垂穗鹅冠草和硬杆仲冰草等4种草。5种草不同生育期营养成分的分析结果表明，各草种分蘖期和孕穗期的粗水分、粗灰分、蛋白质、粗脂肪以及钙、磷含量明显高于结实期，而粗纤维、干物质和除赖草外的无氮浸出物含量则相反。
