Abstract

Observations of the relationship between linear
or planar features on either side of dykes usually
form the basis of a field determination of their
mode of emplacement, although it is known that
sections oblique to planar features may lead to conflicting
results. In Eastern Tasmania only rarely
are examples encountered where dyke wall-rock
units are of use. However, dyke wall irregularities
are common and a comparison of opposite walls
have shown the dykes to be intrusive. Disproportionate
offsets of corresponding wall irregularities
due to connecting cross-dykes are general,
which results in intrusive bodies resembling those
of a replacement origin.
