Lamproite, the other igneous rock in Kansas, is found in a small area along the Woodson and Wilson county line. Although ...
One of the most common rocks found at the park is also one of the rarest to find beyond the borders of the crater. Lamproite is the volcanic material that erupted from the park’s diamond-bearing pipe around 100 million years ago. Four types of lamproite can be found at the park today, but not all are diamond-bearing.Kimberlite is a blue-ish rock that's found almost exclusively in structures known as kimberlite pipes. Kimberlite itself is an igneous rock, and is considered a rare variant of peridotite. Those who are familiar with the formation of peridot know that peridotite is an olivine-rich stone that bears the semi-precious gemstone peridot.Canada is characterised by diverse types of kimberlites with contrasting external pipe shapes and pipe infills (Fig. 1).The variations are attributed to different local country rock geology and emplacement processes (Field and Scott Smith, 1999).The pipes in the Gahcho Kué kimberlite cluster are different from many other Canadian kimberlites …Kimberlite is an igneous rock and a rare variant of peridotite.

Kimberlite is a decorative and priceless Gemstone. It appears in thin vertical ore formations called Kimberlite Pipes which can be up to 60 blocks high.
Kimberlites are volcanic eruptions that bring material from the depths where diamonds can form. Yet, unlike many geologic processes, a kimberlite eruption could launch rocks from the mantle at ...
The meaning of Kimberlite is stability. Kimberlite was called Diamond Rock in earlier times due to the presence of Diamonds. The presence of other crystals in it also earned names like Peridotite Diamond and Olivinite Diamond. Today, this Diamond-Bearing Rock is used for clarity, vitality, grounding, karmic healing, and transformation.Kimberlite is composed of at least 35% olivine, together with other minerals such as mica, serpentine, and calcite (Jackson, 1997). Geologists call it an ultrabasic rock, which means it does not contain any quartz or feldspar, the two most common rock-forming minerals.One of the most common rocks found at the park is also one of the rarest to find beyond the borders of the crater. Lamproite is the volcanic material that erupted from the park’s diamond-bearing pipe around 100 million years ago.
