My stones for discussion. The topic is replenished with new stones.

Hello, I'm new to the forum. I am interested in finding meteorites. I use Google Translate. I'm from Russia. I would like to share photos of my findings. 1. Here is a stone I found at the edge of the village, it is magnetic, heavy, does not leave a trace on the tiles, but scratches it. after polishing it became black. There are blotches of iron. The entire stone is covered with a thin glassy crust. there are voids, cracks. Maybe not a meteorite, there are no factories nearby, there are no mountains, there is sand and loam. Under the microscope, the structure of the stone is visible, it consists of crystals similar to glued black threads. Here on the forum there are people with great experience, I would like to know their opinion whether it is worth sending a stone for examination, or not worrying. And such meteorites do not exist? In Russia, if there are holes in a stone, they immediately say that it cannot be a meteorite. Thanks. photo 8, cut without polishing

Second stone. Found at the edge of a ravine, sand, sandstone. The weight is normal for a stone. It is very difficult to break. The rock is igneous. Not magnetic. Under the microscope, dots of gold color (gold? Or pyrite?) Are sometimes visible. No iron is observed. On the one hand, is the effect of passing through the atmosphere visible? The anterior part of the melting crust. Weight is unknown. Looks like a meteorite? What tests need to be done? There are no bedrocks in the area. The sedimentary layer is over a kilometer.

Third stone. Found in the field. On the one hand, the "melting crust"? Not magnetic. The metal detector responds. There are no bedrocks in this area, the sedimentary layer is more than a kilometer. I also wanted to ask, is it like melting crust by the atmosphere?, Or terrestrial melting at a volcano? Thanks.

Welcome to the site, Pavel...

I am not an expert, but those last 2 stones seem awfully large to
be meteorites.

Hello. There is also a small one. 9 grams. Iron with small, yellow crystals. Found by metal detector

Hello, our search season is over, winter has begun. Thanks to those who answered me. I managed to find a few more small stones, possibly meteorites. Here is 1 of them. The stone has a glass crust on top, the influence of the passage of the atmosphere at the bottom along the edges, and on the side of the fracture, a melting lip can be seen from the top.

One more, has no chondrules, there is a crystalline structure. There is a melting crust with breaks. Perhaps achondritis.?

Another interesting one, iron, highly magnetic. Black, opaque crystals stick out from it. I don’t know if there are such meteorites? Is it pallasite with pyroxene crystals? I would like to hear the opinion of experts.

Hello, could this be a meteorite? many small vitreous chondrules 0.2 mm. 3 centimeters long.
