Description
技术领域
本发明涉及判断古沉积环境技术领域,尤其涉及一种利用硼钙比值及锶钡比值判断古沉积环境的方法。
背景技术
目前判断成矿流体来源(运移)方向的技术主要有:岩石的颜色、沉积构造、岩石结构与粒度、岩石成分、古生物、地球物理、元素比值等。这些方法技术的缺点主要为:工作量大、时间周期长、人财物耗费大、理论性强,不便于普通技术人员掌握。
前人采用的单一的元素比值法为w(B)/w(Ga):小于1.5为淡水相(陆相)、5-6为近岸相,大于7为海相;w(Sr)/w(Ba):小于1为淡水相(陆相)、大于1为海相。
这样会出现同一个岩石的w(B)/w(Ga):小于1.5为淡水相(陆相)、w(Sr)/w(Ba):大于1为海相的两个结果,给研判人员带来较大难度。
发明内容
发明目的
为解决背景技术中存在的技术问题,本发明提出一种利用硼钙比值及锶钡比值判断古沉积环境的方法,利用沉积岩石的元素地球化学的硼(B)、钙(Ca)、锶(Sr)、钡(Ba)值,采用w(B)/w(Ga)与w(Sr)/w(Ba)的和值,能快速判断古沉积环境,为区域建立古地理相提供依据。
技术方案
为解决上述问题,本发明提出了一种利用硼钙比值及锶钡比值判断古沉积环境的方法,包括以下步骤:
S1:收集工作区岩石样品的分析结果,进行数据录入、计算出w(B)/w(Ga)以及w(Sr)/w(Ba)的值;
S2:将岩石样品 w(B)/w(Ga)与w(Sr)/w(Ba)相加后的的结果A进行统计,并绘制在统计分析图上;
即,A=w(B)/w(Ga)+w(Sr)/w(Ba);
S3:判定岩石样品的古沉积环境为陆相还是海相;
当A小于2.5时,判定判定岩石样品为陆相;
当A大于7.5时,判定岩石样品为海相。
优选的,当A为2.5-7.5之间时,判定判定岩石样品为近岸相。
优选的,在S2中,采用Excel软件进行数据录入。
本发明利用沉积岩石的元素地球化学的硼(B)、钙(Ca)、锶(Sr)、钡(Ba)值,采用w(B)/w(Ga)与w(Sr)/w(Ba)的和值,能快速判断古沉积环境,为区域建立古地理相提供依据。
具体实施方式
为使本发明的目的、技术方案和优点更加清楚明了,下面结合具体实施方式,对本发明进一步详细说明。应该理解,这些描述只是示例性的,而并非要限制本发明的范围。此外,在以下说明中,省略了对公知结构和技术的描述,以避免不必要地混淆本发明的概念。
本发明提出的一种利用硼钙比值及锶钡比值判断古沉积环境的方法,包括以下步骤:
S1:收集工作区岩石样品的分析结果,进行数据录入、计算出w(B)/w(Ga)以及w(Sr)/w(Ba)的值;
如表1所示:
S2:将岩石样品 w(B)/w(Ga)与w(Sr)/w(Ba)相加后的的结果A进行统计,并绘制在统计分析图上;
即,A=w(B)/w(Ga)+w(Sr)/w(Ba);
S3:判定岩石样品的古沉积环境为陆相还是海相;当A小于2.5时,判定判定岩石样品为陆相;当A大于7.5时,判定岩石样品为海相。
如表2所示:
由表2可知,砂岩1、砂岩2和页岩3,为陆相沉积;灰岩4为海相沉积。
在一个可选的实施例中,当A为2.5-7.5之间时,判定判定岩石样品为近岸相。
在一个可选的实施例中,在S2中,采用Excel软件进行数据录入,方便快捷。
综上,本发明,利用沉积岩石的元素地球化学的硼(B)、钙(Ca)、锶(Sr)、钡(Ba)值,采用w(B)/w(Ga)与w(Sr)/w(Ba)的和值,能快速判断古沉积环境,为区域建立古地理相提供依据。
