Introduction to Geological Process in Illinois Glacial
INTRODUCTION TO GEOLOGICAL PROCESS IN ILLINOIS GLACIAL PROCESSES AND LANDSCAPES GLACIERS A glacier is a flowing mass of ice. This simple definition covers many possibilities. Glaciers are large, but they can range in size from continent covering (like that occupying Antarctica) to barely covering the head of a mountain valley (like those found in the Grand Tetons and Glacier National Park). No glaciers are found in Illinois; however, they had a profound effect shaping our landscape. More on glaciers: http://www.physicalgeography.net/fundamentals/10ad.html Formation and Movement of Glacial Ice When placed under the appropriate conditions of pressure and temperature, ice will flow. In a glacier, this occurs when the ice is at least 20-50 meters (60 to 150 feet) thick. The buildup results from the accumulation of snow over the course of many years and requires that at least some of each winter’s snowfall does not melt over the following summer. The portion of the glacier where there is a net accumulation of ice and snow from year to year is called the zone of accumulation. The normal rate of glacial movement is a few feet per day, although some glaciers can surge at tens of feet per day. The ice moves by flowing and basal slip. Flow occurs through “plastic deformation” in which the solid ice deforms without melting or breaking. Plastic deformation is much like the slow flow of Silly Putty and can only occur when the ice is under pressure from above. The accumulation of meltwater underneath the glacier can act as a lubricant which allows the ice to slide on its base. -

Libbey Oireotor Pric-e 25 Cents POR&WORD The lightweight aggregate industry which has had auoh a phenoaenal growth since World War II 11 based on the desirabil ity and need of re ducing the weight of structure without sacrificing strength. Although there is plenty of rooa tor 1 aproveaent in praotice through better under standing or the probleaa involved and apec 1rically through greater care in preparation of aaterials , the industry undoubtedly is here to stay and haa aade only a start ln ita developaent. The Departaent hal had a working interest in the developaent of li ghtweight aggregates. Ita work hal been along both geological and engineering lineo in encouraging tho industry'o growth and it ie hoped that loae Departaental proJects now under way will be of further alsiet �ce. The author ot thie paper, Kr. Ralph s. Mason, has done field and laboratory work on ao a t or the aateriala now used as lightweight aggre gates or a• building atones. He has prepared Jointly with Kr.

ISSN 0309-2199 NOTES ON MINING LEATS R.H. Bird “.... the means of putting to work many mines that would otherwise remain unworked, or if worked, could not be worked with profitable results.” Absalom Francis. 1874. SYNOPSIS Watercourses supplying mining works have been in use for centuries but their complexity increased during the 19th century, particularly in mining districts which were remote from coal supplies used for steam engines but which had sufficient river systems (or streams) of a dependable nature. Their role in Britain’s mining areas is discussed, with examples from overseas locations. An attempt is made to outline their construction methods and costs. In an age when water power reigned supreme and, indeed, for some time thereafter, mills and manufacturing industries were dependant on a steady supply of water to drive that prime mover, the water wheel. Flour mills, fulling mills and the early ferrous metal industries were sited next to reliable river or stream courses and could thus utilise this water source with little difficulty. Sometimes, the configuration of the stream was inconveniently placed for the mill site and the miller was forced to construct a ditch, from a dam upstream of his mill, and by this, lead the water to his wheel. After driving the wheel, the water was returned to the stream directly or through another ditch, the tailrace. -

Bluth, M.S. Department of Geology and Planetary Science University of Pittsburgh, 2004 Phreatomagmatic fall, low-concentration PDC deposits and remobilized equivalents dominate the products of craters (tuff cones/rings) of Koko fissure, south-east Oahu. At Koko crater, Fisher (1977) described “U-shaped” channels, which he interpreted as due to erosion by low-concentration PDCs (surges), with minor modification by stream and debris flows. Similar channels on tuff cones and rings elsewhere in the world have been interpreted as “surge-eroded” by subsequent authors. However, no evidence for erosion by PDCs was observed during recent fieldwork, which suggested rather the following model. An important observation is that initial incision is always correlated with the emplacement of vesiculated ash layers (derived from Hanauma Bay), and is only very rarely associated with other facies. -

A Glacier Runs Through It: Effects of Late Wisconsinan Glaciation on Stream Drainage Near the Terminal Moraine Boundary in North Central Pennsylvania Abstract Stream morphology in north central Pennsylvania has been influenced yb the passage of multiple glaciers during the Quaternary period, and most recently by the Late Wisconsinan ice sheet which began to recede just 10,000 years ago. While glaciers can take a heavy erosive toll on the landscape, the Late Wisconsinan and previous glaciers stopped when they reached Pennsylvania, and as such were not as thick and did not cover the ground as long as in regions to the north. This paper examines current morphology in an area along the north central part of the state that contains both glaciated and non-glaciated regions. -
