Greenstone vs. Serpentine — What's the Difference?
Edited by Tayyaba Rehman — By Urooj Arif — Updated on April 3, 2024
Greenstone vs. Serpentine: Greenstone is a broad term for metamorphic rocks rich in green minerals, while Serpentine refers to a group of minerals forming green to greenish-black rocks.

Key Differences
Greenstone encompasses a wide range of metamorphic rocks that are green due to their chlorite, actinolite, and epidote content. These rocks are typically formed under low-grade metamorphic conditions and can include various rock types like schists and basalts. Serpentine, on the other hand, specifically refers to a group of minerals that are commonly found in metamorphosed ultramafic rocks. These minerals are characterized by their green color and smooth or scaly appearance.
Greenstone's green color primarily comes from chlorite, actinolite, and sometimes epidote, which are formed under specific metamorphic conditions. This gives greenstone its distinctive greenish hue. Serpentine minerals also impart a green color to rocks, but this comes from magnesium iron silicate minerals that have undergone hydrothermal metamorphism. The color and texture of serpentine are unique, ranging from translucent to opaque and from smooth to fibrous.
In terms of geology, greenstone belts are significant as they often contain valuable mineral deposits such as gold and copper. These belts represent ancient volcanic zones where the greenstones were formed. Serpentine rocks, however, are often associated with the presence of asbestos, a hazardous material, and are less known for containing valuable ores. The formation process of serpentine involves the alteration of ultramafic rocks from the Earth's mantle, making it common in ophiolite complexes.
From a cultural and historical perspective, both greenstone and serpentine have been valued for their beauty and durability. Greenstone, especially in New Zealand where it is known as pounamu, holds great cultural significance to the Māori people and is used in carvings and jewelry. Serpentine has been used in decorative arts and architecture, valued for its attractive green color and patterns.
The environments where greenstone and serpentine form are quite different, leading to distinct ecosystems. Serpentine soils, derived from serpentine rocks, are known for their high magnesium and low calcium levels, which can be toxic to many plants. However, these soils also support unique plant communities adapted to these conditions. Greenstone, being less chemically distinct from its surroundings, does not have as pronounced an effect on the local ecology.
