Crustal Reflection

Between 1976 and 1978 the Australian Bureau of Mineral Resources (BMR) recorded deep crustal reflection data at seven sites in northeastern Australia over continuous profiles up to 15 km long by simply extending the recording time to 16 sec during normal sedimentary basin surveys. The record sections show many events with variable strength, continuity, dip, and spatial distribution. By comparing the sections from the longer and the shorter perpendicular traverses, it is possible to discriminate between primary reflections and diffractions, multiples, and other noise events. Based on their character the reflections can be grouped into zones which are interpreted in terms of the nature and structure of the crust. Most of the reflection sections show, below the sedimentary reflections, a thin (2–3 sec) reflection‐free zone underlain by a thick (9 sec or more) zone of numerous reflection segments which varies in thickness and the distribution of reflection segments. The data thus suggest that the upper crust under the sediments is similar in seismic character throughout northeastern Australia. On the other hand, the deeper crust under the Georgina and Drummond basins is significantly different in seismic signature and thickness from that under the Bowen basin and the northern margin of the Galilee basin. It is concluded that good quality deep reflections can be recorded with little extra effort during sedimentary basin surveys using modern multiple‐fold common‐depth‐point (CDP) techniques, and that the data recorded on long traverses, cross‐spreads, and expanded spreads provide information on the structure and composition of the crust and upper mantle with a resolution greater than has been possible before. Such information is valuable in studying the evolution of mineral and petroleum provinces and the lithosphere in general.

Crustal Reflection

Before the Consortium for Continental Reflection Profiling (COCORP) deep crustal reflection profile across the Wind River range, Wyoming, can be understood, problems involving velocity, multiple reflections, and structural style associated with thrusting must be resolved. Measurements from boreholes to maximum depths of 7.8 km show that a strong velocity inversion is associated with overpressured zones, primarily in Cretaceous shales. One‐dimensional (1-D) synthetic seismograms generated using the detailed velocity distribution closely duplicate the seismic trace on line 1 and produce multiple reflections of significant amplitude to record times of l0 sec. Other data including auto‐correlograms demonstrate presence of abundant multiple reflection energy to times of 10 to 12 sec on lines 1 and 2 and suggest that most of the deep events on these lines are multiple reflections. Because this area has not been known as a problem area for multiples in shallow (industry) reflection surveys, we conclude that multiples are a greater impediment for deep crustal reflection studies than has previously been recognized and that the sedimentary section must be treated much like the weathered zone in shallow seismic studies. Two‐dimensional (2-D) modeling and hand migration are used to determine structure in sedimentary rocks beneath the thrust Precambrian wedge. They suggest that structural as well as velocity uplift is found under the thrust, that a wedge of overturned sedimentary rocks parallels the thrust, and that the deeper sedimentary rocks bend down into the thrust.

Forearm pass is one of the materials that must be mastered by students of class X Senior High School. In fact, many students do not yet master and know forearm pass techniques. This research is a classroom action research (CAR) with two cycles. Each cycle consists of 4 stages, namely: planning, action, observation and reflection. Data collection was carried out using observations and questionnaires. Data were analyzed using Hake's Normalized Gain formula. From the results of the study it is known that the psychomotor domain of students increased by 0.42 with average criteria from cycle 1 to cycle 2. The affective domain increased by 0.37 with average criteria. The cognitive domain increased by 0.39 with average criteria. Based on the results of the data analysis, it can be concluded that learning forearm pass techniques with games method can improve student learning outcomes.

In the background backs Indonesian learning results obtained by the students is very low because the method of learning that are not relevant. Classroom action research aims to determine the implementation of cooperative learning model Numbered Heads Together (NHT) to improve learning outcomes Indonesian grade IV A SD Negeri 78 Pekanbaru on instructional materials do. The experiment was conducted in two cycles each cycle two meetings and one daily tests. Each cycle stages are: planning, implementation, observation and reflection. Data from the activity of teachers and students in the can from the observation sheet, while, learning outcomes in getting the daily test results. The results showed the activities of teachers and students has increased, in the first cycle of meetings I obtained a score of 33 (68.75%), in the first cycle of meetings II obtained a score of 38 (79.17%), the second cycle of meetings I obtained a score of 40 (83 , 33%), and the second cycle II meeting obtained a score of 44 (91.67%). And in the first cycle of the first meeting of student activity data obtained a score of 27 (56.25%), in the first cycle II meeting increased with the acquisition of a score of 36 (75.00%), and the second cycle first meeting increased to 41 (85.42 %), the second cycle II meeting increased to 45 (93.75%). Learning outcomes of students has increased, this is evidenced by: the preliminary data the number of students who reach KKM amounted to 10 students (28.57%) with an average of learning outcomes at 65.37. Increased in the first cycle by the number of students who completed totaling 26 students (74.28%) with an average of learning outcomes at 76.00. And the second cycle increases with the number of students 32 students (91.42%) with an average of learning outcomes at 86.86. Based on these results it can be concluded that the implementation of cooperative learning model NHT can improve learning outcomes Indonesian grade IV A SD Negeri 78 Pekanbaru.
