The Ampasibitika Intrusion, located around the village of Ampasibitika at the southeastern coast of the Ampasindava peninsula in the northwestern part of Madagascar, is a part of the Cenozoic Ambohimirahavavy alkaline complex (Estrade et al., 2014). The intrusion consists of peralkaline granitic dikes (fasibitikite) intruding mudstone and limestone of the mesozoic Isalo Group.

Most of the minerals listed are found in dikes peralkaline granite of different variation, the most known is a rare-metal taxitic or foliated aegirine-riebeckite granite, a rock A. Lacroix (1922) named "fasibitikite".

A Russian funded Soviet Geological Mission was prospecting in the area between 1988 and 1991 ("Ampasibitika prospect").
Around 2011-2014 (?) the Ampasibitika Intrusion was explored by the Tantalus Rare Earths AG.

Geochronology

Mineralization age: Oligocene : 24.2 ± 0.6 Ma

Important note: This table is based only on rock and mineral ages recorded below and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
