Follow-up Question

Complete this identification chart for metamorphic rock using the chart below and find the following mineral present, texture, type of metamorphism, Portolith, and rock name

Rock sample #35

The image shows a sample of a mineral or rock displayed on a textured surface. The mineral appears to be black with a shiny, metallic luster, possibly indicating the presence of a metallic ore like galena or another sulfide. The sample is irregularly shaped, with some sharp edges and a somewhat crystalline structure.

A small circular label with the number "35" is attached to the mineral, likely for identification or cataloging purposes, typical in educational or museum settings.

The background consists of dark, textured material, providing contrast to the mineral sample, making it stand out visually for easier examination and study.

This image can be used to study mineral properties, including luster, color, and texture, and to aid in the learning of mineral identification techniques.

Rock sample #34

The image shows a mineral sample labeled with the number "34". The sample appears to have a rough texture and a greenish-gray color. It is placed on a textured, dark surface, likely intended to highlight the features of the mineral. There are no additional diagrams or graphs in the image. The labeling suggests this sample might be part of a larger collection, possibly for educational or research purposes.
