We will also provide you with a $200 discount code for the LMAC classification services which are normally $500 per analysis sample. This offer is only valid if you use LMAC for the analysis and classification services. There is no obligation to classify the meteorite if you purchase it. This is a completely optional value added offer for those who want to take it to the next step. If you do decide to take advantage of this offer, contact us after purchasing the specimen and we will provide more details and instructions on how to proceed with the classification process. \u003cbr\u003e\u003cbr\u003e\u003cb\u003eThe Chondrites\u003c\/b\u003e\u003cspan\u003e \u003c\/span\u003eare undifferentiated\u003cspan\u003e meteorites\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003ethat have not been modified due to\u003cspan\u003e melting\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003eor\u003cspan\u003e differentiation\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003eof the parent body.\u003cspan style=\"font-size: 12.5px;\"\u003e \u003c\/span\u003eThey are formed when various types of dust, water ice, small mineral grains, chondrules and chondrule fragments present in the early solar system accreted to form primitive\u003cspan\u003e asteroids\u003c\/span\u003e.

Each of these three types are then given petrological grades between 3 and 7 depending on how equilibrated they are, with 3 being the least equilibrated and 7 being the most equilibrated. There are several less common types of chondrites including; Carbonaceous Chondrites (C), Enstatite Chondrites (E), Rumuruti-like Chondrites (R), and Kakangari-like Chondrites (K). \u003c\/span\u003eThe study of the ordinary chondrites and the other types of chondrites provides important clues for understanding the origin and age of the\u003cspan\u003e Solar System,\u003c\/span\u003e the synthesis of\u003cspan\u003e organic compounds\u003c\/span\u003e, the\u003cspan\u003e origin of life, and\u003c\/span\u003e how Earth got its water\u003cspan\u003e.\u003c\/span\u003e One of the key characteristics of the chondrites is the presence of\u003cspan\u003e chondrules,\u003c\/span\u003e which are complex spherical mineral grains, often glassy and having gone through multiple rapid heating events.
