The fall of a meteorite shower in Parambú, Ceará State, Brazil, is described. Parambú is an L‐group chondrite (Urey and Craig, 1953). The mineralogical composition is olivine Fa 28 . ortho‐ and clinopyroxenes, plagioclase, maskelynite, whitlockite, nickel‐iron, troilite, chromite, and ilmenite. The structure of Parambú is characteristically polymict and shows an advanced brecciation. Interesting features of metamorphism are notable, with good evidence of shock.
