Ourique is an H4 chondrite that fell in Portugal and one of the rare instances a meteorite falls in Portugal in recent times.

Allende is a historic CV3 carbonaceous chondrite that fell in Mexico and the largest carbonaceous chondrite to ever fall and to have been recovered with 2,000 kg of recovered material, it is the most well-studied meteorite too.

Tirhert is a rare monomictic eucrite that fell in Morocco known for the glossy black fusion crust.

Tsarev is a highly underestimated L5 ordinary chondrite that is the largest recorded fall of a stony meteorite in Russia, followed by Chelyabinsk.

Northwest Africa 11228 is a cool lunar feldspathic breccia found in Morocco around late 2016 to 2017.

Edit: NWA 11228’s total known mass is 0.14 kg, not g.
Also, Ourique is the hardest to get here, there’s limited stuff for Ourique available in the market. I haven’t heard of this until I searched “Portugal meteoritesl.

Classified as monomictic eucrite, don’t know why it’s like that in the photo, but the crust is so shiny in person, very glossy.

Daule is classified as L5 ordinary chondrite
Thuathe is classified as H3-4 ordinary chondrite
Lost City is classified as H5 ordinary chondrite

Stony-iron meteorites are meteorites consisting of roughly equal parts of silicate (olivine for pallasites, and others with mesosiderites) and iron matrix. There are two main groups: Pallasite and Mesosiderite.

Pallasites have these classes within them: PMG (main group), PMG-an (main group, anomalous) and Eagle Station Group.

Mesosiderites have 3 classes: Class A (eucrite-like, high clinopyroxene/plagioclase and high amounts of trace elements like Gold, Nickel, Arsenic and Copper);
Class B (diogenite-like, greater orthopyroxene) and Class C (made nearly entirely out of orthopyroxene).

But we’re going to talk about pallasites in this post.

A pallasite meteorite is an exceptionally rare type of stony-iron meteorite that consists of translucent, gem-quality olivine (peridot) crystals suspended in a shimmering nickel-iron metallic matrix.

Pallasites are highly sought after by collectors and jewelers because of their stunning, stained-glass-like appearance when cut and polished. Sometimes some pallasites are etched.

Scientists believe pallasites originated at the core-mantle boundary of differentiated asteroids. During the early formation of the solar system, heavy iron and nickel sank to the center of these planetesimals, while lighter silicates (olivine) floated to the top.

Pallasites make up less than 0.5% of all known meteorites of any type, making them rare.

Examples of pallasites other than Seymchan are Sericho, Springwater, Eagle Station, Cold Bay, Esquel, Fukang, Imilac, Omolon and other Northwest African pallasites.
