4.91 grams.   CV3

TKW 1578 grams. Fall not observed. Purchased May 2022 from a dealer in Algeria.

From the MetBul:

History: The meteorite was purchased from a meteorite dealer in Algeria.

Physical characteristics: Six dark brownish fragments lacking fusion crust.

Petrography: Carbonaceous chondrite composed of large chondrules (up to 2 mm sized), CAIs (up to 3 mm sized), and olivine amoeboids all set into a fine-grained dark brownish matrix. Some chondrules show brownish-reddish staining due to terrestrial alteration. Opaque phases include magnetite, rare FeNi metal, and their respective alteration products.

I'm from Brazil and I love meteorites. I took these images with a petrographic microscope using incident light and 4x magnification.

Heriton, very interesting specimen to scope. What you are doing is working very well. When I scope, I've spent long periods of time on one square inch. Sometimes, a small 5000k hand held flashlight held at just the right angle will perfectly highlight an area of interest. You're good, keep playing with it. You may find that a counterintuitive innovation produces the desired result. Heard of a guy that used plastic dishwasher drain hose to solve his issue. Rock on.
