据估计,石炭纪的持续时间为65年,从345年延长到280年。那是以前的事了。利用对具有不同程度地层控制的沉积物、同时代火山岩和侵入岩进行的年龄测定,提出了一个暂定的石炭纪时标。就大多数关键数据都与或可能与之相关的欧洲标准继承人而言,情况如下:
Summary It is estimated that the duration of Carboniferous time was 65 m.y., extending from 345 to 280 m.y. ago. Using age-determinations made on sediments, contemporaneous volcanic rocks, and intrusive rocks that have varying degrees ofstratigraphical control, a provisional Carboniferous time-scale is proposed. In terms of the standard European succession, to which most of the critical data pertains or can be related, it is as follows:
