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 ...

Lake Henshaw is a reservoir in San Diego County, California, at the southeast base of Palomar Mountain, approximately 70 miles (110 km) northeast of San Diego and 100 miles (160 km) southeast of Los Angeles.
Lamproite pipes operate similarly to kimberlite pipes, except that the boiling water and volatile compounds contained in the magma act corrosively on the overlying rock, resulting in a broader cone of eviscerated rock (the ejection of this rock also forms a tuff ring, like kimberlite eruptions). This broad cone is then filled with volcanic ash ...
Examples of xenocrysts are quartz crystals in a silica-deficient lava and diamonds within kimberlite diatremes. Xenoliths can be non-uniform within individual locations, even in areas which are spatially limited, e.g. rhyolite -dominated lava of Niijima volcano ( Japan ) contains two types of gabbroic xenoliths which are of different origin ...
Chrome diopside ((Ca,Na,Mg,Fe,Cr) 2 (Si,Al) 2 O 6) is a common constituent of peridotite xenoliths, and dispersed grains are found near kimberlite pipes, and as such are a prospecting indicator for diamonds. Occurrences are reported in Canada, South Africa, Russia, Brazil, and a wide variety of other locations.
El Mirage Lake is a dry lake bed in the northwestern Victor Valley of the central Mojave Desert, within San Bernardino County, California. The lake is located about 9 miles (14 km) west-northwest of the town of Adelanto and 10 mi (16 km) north of Highway 18 in San Bernardino County .
Occurrences of ultramafic tuff include surface deposits of kimberlite at maars in the diamond-fields of southern Africa and other regions. The principal variety of kimberlite is a dark bluish-green, serpentine-rich breccia (blue-ground) which, when thoroughly oxidized and weathered, becomes a friable brown or yellow mass (the "yellow-ground").
