9350939 Freed The Geology Department is using a Philips PW 1840 automated X- ray diffractometer system which to enhance both undergraduate courses and undergraduate research. The goal is to integrate use of the diffractometer into three components of Trinity's science curriculum: (1) the beginning Physical Geology course; (2) the geology major, specifically student research projects and three required sequential courses for the major (Mineralogy & Crystallography, Igneous & Metamorphic Petrology, and Stratigraphy & Sedimentation); and (3) laboratory exercises in engineering and physics classes (Engineering Materials and Condensed Matter Physics). Beginning geology students use modern analytical X-ray equipment as an integral part of examining minerals and rocks. Advanced students are using the instrument to study mineral identification techniques, understand crystallographic relationships, investigate compositional and structural variations in minerals, and work with multiple-phase systems, such as sediments or fine-grained igneous or metamorphic rocks. After completing the required course sequence, geology majors have the experience necessary to use the diffractometer for addressing mineralogical problems in a research context. The diffractometer significantly expands the types of research projects that students can undertake. ***

9350939释放地质系正在使用飞利浦PW 1840自动X射线衍射仪系统，以加强本科课程和本科研究。目标是将衍射仪的使用整合到Trinity的科学课程的三个组成部分中：（1）开始的物理地质学课程;（2）地质学专业，特别是学生的研究项目和三个主要的必修课程（矿物学晶体学，火成岩变质岩石学和地层沉积学）;和（3）工程和物理课程的实验室练习（工程材料和凝聚态物理学）。开始地质学的学生使用现代分析X射线设备作为检查矿物和岩石的一个组成部分。高级学生正在使用该仪器学习矿物鉴定技术，了解晶体学关系，研究矿物的成分和结构变化，并使用多相系统，如沉积物或细粒火成岩或变质岩。在完成所需的课程序列后，地质专业的学生有必要使用衍射仪在研究背景下解决矿物学问题的经验。衍射仪显着扩大了学生可以承担的研究项目的类型。 ***
