Exploration techniques for kimberlites primarily hinge on the identification and analysis of indicator minerals associated with the presence of kimberlite pipes and their potential diamond content. Sediment sampling is a fundamental approach, where kimberlite indicator minerals (KIMs) are dispersed across landscapes due to geological processes ...
The Wilson and Tesla kimberlites contain both tuffisitic and hypabyssal kimberlite. [10] Lastly, the 5034 kimberlite is located directly under Kennady Lake, which was also the first kimberlite to be discovered at Gahcho and dominates in Hypabyssal Kimberlite. All five kimberlites have a life expectancy until 2028. [9]
The NAKP kimberlite fields are located about 350 km (220 mi) to 450 km (280 mi) north to northwest of Edmonton in an area bounded by 55° and 57°N latitude and 115° and 118°W longitude. The area lies within the Canadian boreal forest and is sparsely settled.
The Lake Ellen Kimberlite is a poorly exposed volcanic breccia located about 10 miles (16 km) northeast of Crystal Falls in the Upper Peninsula of Michigan. The first publication in 1981 [ 1 ] describing the feature led to speculation that this or similar kimberlites in the area might have been the source of the diamonds discovered a century ...
Deep beneath the BHH kimberlite field lies a 2.0 to 2.4 billion year old Precambrian craton called the Buffalo Head terrane, which has no exposure at surface.The Precambrian craton is overlain by about 1,600 m (5,200 ft) of Paleozoic and Mesozoic sedimentary rocks, which are covered by as much as 200 m (660 ft) of unconsolidated glacial and post-glacial sediments of Quaternary age.
