Software and sponsors are mentioned below. The characteristical fabric is due to quartz aggregates which are intergrown with a potassium feldspar matrix in an oriented manner. 44kB, JPEG reduction Cryptic granite 3-D reconstruction. The rock fabric, represented as a voxel array, has been thresholded to yield 3-D surface models of the fossils. Fossils visible are different nautilides and ammonites.
White arrow indicates isolated ammonite shown below.
Isolating a single ammonite from the volume model of the fossiliferous limestone and slicing through it to visualize internal structures. 78kB, JPEG reduction Doleritic basalt 3-D reconstruction. Garnet hornblende schist fabric 102kB, JPEG reduction Desktop scanned true color image of a garnet hornblende schist. Elongated, dark green hornblende needles and dark brownish-red garnets in a light grey matrix of plagioclase and quartz. For better visualization, part of hornblende aggregates have been removed, matrix is invisible.
