Hammadah al Hamra 280 - CK4 Carbonaceous Chondrite

Hammadah al Hamra 280, often abbreviated to HaH 280, is a rare CK4 Carbonaceous Chondrite found in Libya in 2000. As a CK Carbonaceous Chondrite, it represents primitive solar system material that has also experienced significant thermal metamorphism on its parent body. Its type 4 classification indicates that original Chondritic features are still present, but have been modified by heat and recrystallisation over time.

HaH 280 specimens typically show a dark, compact matrix with subdued chondrules and oxidised mineral features characteristic of the CK group. Compared with less altered Carbonaceous Chondrites, it has a more thermally processed appearance, often with a dense, dark grey to black interior. Its recorded shock and weathering history also reflect both impact processing before arrival on Earth and terrestrial exposure after landing.

Studying Hammadah al Hamra 280 provides insight into how heat alters primitive Carbonaceous material while preserving its broader chemical identity. For collectors, it offers a scarce and well-documented Libyan CK Chondrite with strong scientific interest and a distinctive appearance. Each specimen represents ancient asteroid material from the early solar system, altered by heat and preserved as part of a rare Carbonaceous group.
