摘要
对规则网的 469个测站的多金属结核丰度和 93个测站的 Mn、 Cu、 Co、 Ni元素进行趋势面分析 ,经 F检验 ,各变量的变异性显著 ,拟合度较低 ,表明多金属结核丰度及 Mn、Cu、Co、Ni金属元素的控制因素比较复杂。趋势面分析结果与相关分析结果一致 ,Mn、Cu、Ni元素有极相似的趋势特征 ,有两个轴向分布 ,一个为东西向轴 ,高值区在东部 ,另一个为北西向轴 ,高值区在北西部 ;结核丰度与 Co也有极相似的趋势特征 ,高值区在西部。应用逐次趋势面分析的结果将结核丰度的地质特征分解成各种简单控制因素的叠加 ,使对多金属结核的控矿因素。
Trend analysis on the abundance of polymetallic nodule from 469 sampling stations of regular net and on Mn, Cu, Co and Ni in the nodule from 93 sampling stations are made and \%F\% test shows that every variable varies notably and goodness\|of\|fit is low, which indicates that the control factors of the grade and abundance of the polymetallic nodule is complicated The result of trend analysis is consistent with that of related analysis The trend feature of Mn, Cu and Ni is very similar There are two axial distributions One is from east to west with the high value in the east; the other is from northwest to southeast with the high value in the northwest The nodule abundance and Co share similar trend feature too with the high value in the west The geological features of the nodule abundance resulted from successive trend analysis were decomposed into different simple controlling factors, of which the superposition diversifies the methods to study the controlling factors, distribution rules and material sources of the nodule.
