You may think they mean the same thing but to your skin, it's no ambiguous area for it.
They both are a product of erosion caused by the movement and melting of glaciers. The eroded minerals and elements make their way into the streams and rivers created by the glaciers and the very fine particles are suspended in the water and carried downstream until they reach the ocean.
These particles are what cause the colour of the water in the area of glaciers to be bluish-green in colour. Once exiting the faster flowing water of the rivers and streams, the heavier particles will settle in the faster moving current of the streams (Glacial Clay), only leaving the lighter mineral-rich material to flow into the inlets. Once settled outside the streams and in the ocean over time, these particles will form a deposit and become a very dense and hard-packed layer(Glacial Marine Clay).
This hard-packed layer will not allow vegetation to grow within it or any crustaceans to survive in it. However, phytoplankton, which is miniscule free-floating plant material, are found in abundance within clay deposits. This phytoplankton enriches the clay and is very beneficial. Non-marine glacial clay deposits do not benefit from daily phytoplankton replenishment/enrichment*.
- In contrast to glacial marine clay, glacial clay is clay formed in the same manner however the particles have settled in areas of streams, rivers, and lakes before reaching the sea, not having contact with any marine nutrients.
- Glacial clay is much more abundant but can have tremendous amounts of sand and grit that needs to be screened out as, generally, the finer particles go downstream and the larger grains settle.
Lowen's Canadian Glacial Marine Clay Mask, EWG approved. Starts with Canadian glacial marine clay harvested in BC, Canada as the main ingredient. Hydresia® Oleosomes helps bring the active ingredients deep into skin tissue.
* phytoplankton population enriches the systems with oxygen through photosynthesis during daylight hours and lowers the levels of carbon dioxide, ammonia, nitrite, hydrogen sulfide, methane etc. A healthy phytoplankton bloom can reduce toxic substances since phytoplankton can consume ammonia-nitrogen and tie-up heavy metals.
