Outcrop Features of the Mansfield Formation in Southwestern Indiana

Indiana Geological Survey Report of Progress 26The Mansfield Formation of early Pennsylvanian age crops out in an area of approximately 1,700 square miles in southwestern Indiana. Three-fifths of the formation consists of sandstone; most of the remainder is finer clastic rocks. Limestone, chert, coal, and iron ore make up approximately 2 percent of the formation. Many similar rock types are found among the several formations upon which the Mansfield unconformably rests, but the assignment of questionable outcrops either to the Mansfield Formation or to an older formation can usually be accomplished with some confidence, because many outcrops contain either diagnostic rock types or indicative rock features. The various rocks of the Mansfield Formation are, for the most part, arranged in a crudely cyclic pattern. The several cyclic units of a region tend to be similar in makeup and different from those of adjacent regions. Three lithofacies that reflect these areal variations can be recognized and are here named: the Shoals Lithofacies is characterized by cross-stratified sandstones, the Bloomfield Lithofacies by gray shales, and the Cannelton Lithofacies by mudstones and thick clays. The distribution of these lithofacies suggests that these rocks were deposited at or near the shoreline, that there was a fairly large delta in the southern part of the outcrop area, and that this delta was an important factor controlling the sedimentary pattern during early Pennsylvanian time.Indiana Department of Conservatio

Nano-scale analysis of titanium dioxide fingerprint-development powders

Titanium dioxide based powders are regularly used in the development of latent fingerprints on dark surfaces. For analysis of prints on adhesive tapes, the titanium dioxide is suspended in a surfactant and used in the form of a small particle reagent (SPR). Analysis of commercially available products shows varying levels of effectiveness of print development, with some powders adhering to the background as well as the print. Scanning electron microscopy (SEM) images of prints developed with different powders show a range of levels of aggregation of particles. Analytical transmission electron microscopy (TEM) of the fingerprint powder shows TiO2 particles with a surrounding coating, tens of nanometres thick, consisting of Al and Si rich material. X ray photoelectron spectroscopy (XPS) is used to determine the composition and chemical state of the surface of the powders; with a penetration depth of approximately 10nm, this technique demonstrates differing Ti: Al: Si ratios and oxidation states between the surfaces of different powders. Levels of titanium detected with this technique demonstrate variation in the integrity of the surface coating. The thickness, integrity and composition of the Al/Si-based coating is related to the level of aggregation of TiO2 particles and efficacy of print development
