For an introductory college-level physical geology class: a review of how to classify and identify a metamorphic rock. Includes a discussion of foliation and other clues to look for in a rock to indicate the intensity or grade of metamorphism to which the rock was subjected. Reviews how to identify each of the following rocks, including what the rock used to be (parent rock) and what was the metamorphic setting in which each rock formed: marble, quartzite, hornfels, skarn, migmatite, gneiss, schist, phyllite, slate, serpentinite, eclogite, and greenstone.
**This video comes near the middle of the semester, so there may be terms with which the audience is unfamiliar. In fact, it is recommended that you watch this video only AFTER watching Identifying Minerals, Identifying Igneous Rocks, and Identifying Sedimentary Rocks. This video reviews ALL those rock types and discusses how they transform into a new metamorphic rock. It can be overwhelming if you start first with this video. For a full playlist, refer to the Geology playlists on the Earth Rocks! RU-vid Channel.
Content within this video is based on information available in any standard introductory college geology textbook (or lab manual), such as Essentials of Geology -- Tarbuck and Lutgens -- Pearson Publishing.

This is the best video on metamorphism I have seen. I have extensive chemistry background, so it may be that the way things are explained here makes sense because I think of the world in terms of atoms and their movement and rearrangement. I think this is the most fascinating and helpful video on explaining mineral formation and and metamorphism at an atomic level that I have found, and I've watched upwards of 30 or 40 videos just on this topic. Thank you SO MUCH!

Very informative video.👍 I have a question please. How are there alternate layers in metamorphic rocks? How is there a black, then light, then black band in Gneiss for example? Is this like nature is also conscious about color combinations.😁 How do they arrange like this?
@EarthRocks
@EarthRocks 5 лет назад
Density -- the darker minerals are denser than the lighter ones. When the crystals are given some energy through heat, they can move around a bit and will separate in bands by density. We see the same thing with sand grains settling on a hillside.

I have spent most of my adult life scouring our local deserts in the great Southwest San Diego and Mexicali and Calexico. There are areas that are restricted to all people along the old Butterfield stage Road. I have ventured into these areas with great caution and there are no signs of indigenous habitation. Back in the 1400s it was reported that this area was inundated by the sea of Cortez. I have found many large Jipson crystals and igneous rocks associated with volcanic activity yet the one element that confounds me are the manganese nodules in small piles strewn about. I sent several samples to be analyzed and they came back as 98% pure manganese the rest being iron. So my question is, how does manganese nodules form in ancient oceans and seas?
@EarthRocks
@EarthRocks Год назад
Manganese nodules form on the bottom of the seafloor as waters are supersaturated with dissolved Manganese. It may be you're finding some deposits left behind as old seafloor rocks have eroded/weathered. Manganese oxides also form as part of the chemical weathering process when minerals dissolve (especially in the desert), but that just creates a stain on the surface (desert varnish). I bet on the old seafloor deposits. You can see them described in part of my Ocean Sediments video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-COz4XiqmQ1Y.html
@stephenrocks7004
@stephenrocks7004 Год назад
@@EarthRocks my surname is Rocks, and my Christian name is Stephen. So as much as I enjoy Rock hunting, my college degree was in chemistry. I hear now that industry is looking for manganese deposits in the search for rare earth metals. The samples I turned in for analysis showed two elements, manganese at 99% and iron at one. So why are they looking for manganese when there is one percent left over as iron and possibly a fraction. And of that could be rare earth. So what am I missing in this equation? as a neophyte ?

@EarthRocks

Continents don't subduct. So when two continents collide, they create massive mountains with deep roots, but no subduction. Only when one of the converging plates has ocean crust at the boundary will there be subduction.

@@surajpatel3044 Yes, subduction brought two continents together. The subducting Indian plate had continental crust attached to the ocean crust, and once the portion of the plate with the ocean crust had completely subducted, the continental portion collided with Eurasian plate and formed the Himalayas. So subduction brought the two together. See the Plate Tectonics Global Impacts video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Y5aMnRGVp_8.html (look at 7:14 onward). And you're welcome. :)

so if a rock has foliation, it's always a metamorphic rock?
@EarthRocks
@EarthRocks 5 лет назад
Not necessarily, but usually. Sedimentary rocks can have layering, and as pressure is added, that layering can turn to foliation (the clay minerals in the sediment align). So some sedimentary rocks that are grading into metamorphic through addition of small amounts of pressure can be foliated. But that's a gray area (the zone when sedimentary turns into metamorphic).
