1. Headland-forming block and matrix, Franciscan broken formation, N. California
Headland-forming block in Franciscan Complex broken formation. Subsequent photos show ever-increasing scales by zooming in on the area of matrix indicated at the 5 foot vertical length of yellow tape measure. See accompanying PDF with mounted photos and comments, and indicated areas of series of "scale shots": Location: MacKerricher State Park near Fort Bragg, Mendocino County, N. California. Photo: E. Medley, 1993
2. Headland McKerricher State PArk
Adjacent headland-forming block in Franciscan Complex broken formation. Compare with previous image: blocks not evident at smaller scale are obvious the area of matrix indicated at the 5 foot vertical length of yellow tape measure. See accompanying PDF with mounted photos and comments, and indicated areas of series of "scale shots". Location: MacKerricher State Park near Fort Bragg, Mendocino County, N. California. Photo: E.

5.2 Franciscan Complex broken formation (B-W version)
Black and white version, suitable for Image Analysis using NIH Image (1993 vintage); same as previous third in a series of photos at ever-increasing scales taken by zooming in on the area of matrix indicated at the 5 foot vertical length of yellow tape measure. See accompanying PDF with mounted photos and comments, and indicated areas of series of "scale shots". Location: Caspar Headlands, near Mendocino, Mendocino County, N. California. Photo: E.

Franciscan Complex broken formation - graphic version for Image Analysis
Monochrome version of the third in a series of photos at ever-increasing scales taken by zooming in on the area of matrix indicated at the 5 foot vertical length of yellow tape measure. Scale independence studies of series of images taken at different scales ultimately incorporated into analysis of scale-independence of some Franciscan Complex melanges. The "dmod" lengh is the longest dimension of a block. See accompanying PDF with mounted photos and comments, and indicated areas of series of "scale shots".

Franciscan Complex sheared shale/sandstone
pervasive shearing in Franciscan Complex bimrock. US quarter coin for scale (y-direction: ~60 up photo from bottom; x-direction 50% of photo to right of left edge). Location: Shelter Cove, Humboldt County, N. California. Photo: E. Medley, 1993.

Franciscan Complex melange, Pacifica, California
Sheared shale with sandstone and white limestone blocks. Limestone content significant enough that the site was the historic Calera quarry that provided cement used in the early construction of nearby San Francisco. Photo: E. Medley, 1994
