在澳大利亚东南部,在南澳大利亚、塔斯马尼亚、维多利亚和新南威尔士各州,现在已经知道有15个相隔很远的金伯利岩和金伯利岩质岩石产区(图1)。野外关系表明,澳大利亚东南部所有这些侵入体的年代都在元古代之后。全岩和金云母同位素年龄测定表明其年龄比较分散。凯拉内拉产地的同位素年龄是最老的,其年龄为早二迭世(～260百万年),这一年龄也为裂变径迹研究所证实。瓦劳威、特罗依、默里迪斯和德利格特产地的年龄分别为中侏罗世和晚侏罗世。初步确定朱吉昂产地的年龄为新生代,不过仍有待检验。
In southeastern Australia, in the states of South Australia, Tasmania, Victoria and New South Wales, there are now 15 kimberlite and kimberlite rock areas that are far apart (Figure 1). The field relationship shows that all of these intrusions in southeastern Australia date back to Proterozoic. Whole rock and phlogopite isotopic age determination shows that their age more dispersed. The age of the isotopes of the Kelanala origin is the oldest, dating back to Early Permian (~ 260 million years), an age evidenced by the Fission Track Research Institute. The ages of the provinces of Valeo, Troy, Merritis and Deligot are middle-Jurassic and Late Jurassic, respectively. The initial determination of the age of Zhuji Ang origin Cenozoic, but still to be tested.
