Serpentinite foliated or nonfoliated.

To identify metamorphic rocks, you will first need to determine if the rock is foliated or non-foliated. Examine the rock for evidence of any pattern or foliation, and if present, identify the size and mineral(s) that compose the foliation pattern ( Figure 13.8, left ).

Serpentinite foliated or nonfoliated. Things To Know About Serpentinite foliated or nonfoliated.

Serpentinite (Fig. 7.12) is a metamorphic rock mostly composed of one or more of the serpentine group minerals that include antigorite, lizardite, and chrysotile.

Non-foliated metamorphic rocks do not have a layered or banded appearance. Examples of nonfoliated rocks include: hornfels, marble, novaculite, quartzite, and ...Texture - foliated. Grain size - very fine grained; grains need to be observed under a microscope; sometimes contains porphyroblasts. Hardness - hard.

Mineralogy - extremely variable, dependent on the original composition of the parent rock.

Both quartzite and marble tend to be pale-colored, non-foliated rock. Despite having a similar appearance, marble is a metamorphic rock made from recrystallized carbonate minerals, not silicates. Marble is softer than quartzite. An excellent test to distinguish the two is to apply a bit of vinegar or lemon juice to the rock.Where antigorite serpentinization is weak, the serpentinite preserves the original peridotite texture (non-foliated). Where antigorite is dominant, the serpentinite possesses both a penetrative foliation and lineation, and is mylonitic. Locally, the serpentinite mylonite wraps around non-foliated zones, as observed in hand samples (Fig. 2 a).
