Journal Article
Published: 01 August 1973
American Mineralogist (1973) 58 (7-8): 802–803.
...Evan R. Phillips Abstract The hypothesis suggested by Shelley (1973) for the origin of a quartz-plagioclase symplectite in the Haast Schists, which are poor in K-feldspar, contrasts markedly with that initially proposed by Shelley (1964) for the genesis of myrmekite. If it is accepted...

Published: 01 August 1973
American Mineralogist (1973) 58 (7-8): 804.
...David Shelley Abstract Rather than commenting on the Haast myrmekites in particular, Phillips raises the following four points for general discussion: how much weight is to be given to the proposed proportionality relationship in myrmekite; is myrmekite poly genetic; are my proposals of 1964...

...David Shelley Abstract Myrmekitic oligoclase grains in the garnet and oligoclase-zone schists of the Haast River differ from common myrmekites in two main ways: (1) they occur in rocks generally devoid of K-feldspar; (2) they are not grain-boundary features but form mosaics often constituting...

In the South Island, the Haast Schist has been displaced horizontally in the Neogene by c. 480 km of dextral‐slip on the Alpine Fault. LS tectonites...
