outcrop geology


But he came to feel defensive about a project so largely based on mapping. He also felt sheepish about having found his thesis topic ‘by chance’ — i.e., by observation — rather than having articulated a problem first and then finding a way to pursue it.

from passage on sedimentologist Francis J. Pettijohn, in Naomi Oreskes her The Rejection of Continental Drift : Theory and Method in American Earth Science (OUP 1999), chapter entitled The Depersonalization of Geology.

Followed, on next page, by this —
...by the 1970s, students were being advised not to pursue outcrop geology — meaning geology in which problems were defined by the outcrop, rather than by the scientist.

(May have parallels in the arts.)
