Sample HB-1

Title: Sample HB-1
Description: The sample is a basaltic igneous rock extruded during divergent volcanism as the result of the break up of Pangea.
Samples were collected by Dr. Kira Lawrence in the Northeast corner of the Meriden Quadrangle (41°37.37'N, 72°44.33'W). The approximate age of the samples based on prior work is ~ 201 Ma.
The sample is a dark gray to black aphanitic basalt with now phenocrysts visible in hand sample. Under 4x and 10x magnification using a petrographic microscope, grains of plagioclase feldspar and pyroxenes can be discerned.
The purpose of this sample being cataloged is to provide a sample for comparison for intrusive samples collected at the Ringing Rocks diabase.
