Fabric Code: tpr110

Shortland feldspathic

Plagiocalse feldspathic sands distinguised by green hornblende. Possibly natural tempering. Microlitic possibly microphanerite. Origin Shortland Is or Bougainville.

Fabric Class:

Feldspathic Igneous-Amphibolic: Dominated by feldspar inclusions, with igneous lithics and amphiboles.

Andesitic Arc: Dominated by andesite and basalt lithic fragments, with microlitic, felsitic and vitric textures, and the andesite minerals (plagioclase, clinopyroxene and sometimes hornblende).

Sites:

Ceramic Wares

Early Shortland (1500 - 1000 BP)

Middle Shortland (1000 - 300 BP)

Late Shortland (300 - 0 BP)
