Summary

[edit]
Description

Picton Kimberlite from the Middle Jurassic of southeastern Ontario, Canada (field of view ~2.1 cm across).

The Picton Kimberlite (informal) is an igneous dike that intrudes the Ordovician-aged Verulam and Lindsay Formations in southeastern Ontario, Canada. It is exposed in the western part of the Picton Quarry in Prince Edward County, at the southeastern margin of Ontario. The nonserpentinized olivine grains making up the bulk of this Picton Kimberlite sample are relatively small. Published research indicates that phlogopite, calcite, spinel, and serpentine are also present. This kimberlite dike was emplaced during the Middle Jurassic.
