NATURE OF THE WORK TO BE DONE. Diatremes are volcanic pipes filled by debris; their surface expressions are called maars. Kimberlites, which often contain diamonds, have many similarities with non-kimberlitic maar-diatreme systems. Canada is now known to host numerous kimberlites and is rapidly becoming a major player in the diamond industry. The research program will combine field studies of very well-exposed relatively fresh diatreme deposits, innovative laboratory experiments, and careful volcanological investigations of diamondiferous kimberlite pipes.

待完成工作的性质。Diatremes是火山管道充满碎片;他们的表面表现被称为maars。金伯利岩，其中往往含有钻石，有许多相似之处，与非金伯利岩maar-diatreme系统。众所周知，加拿大现在拥有许多金伯利岩，并正在迅速成为钻石行业的主要参与者。该研究计划将结合联合收割机非常暴露的相对新鲜的diatreme存款，创新的实验室实验，并仔细的含金刚石金伯利岩管道火山学调查的实地研究。
