项目摘要
My research focuses on the interplay between tectonism and the formation of mineral deposits along the active margins of continents. Continental margins are geological complex, and are commonly the locus of a wide variety of tectonic processes, including the subduction of oceanic crust and resulting development of volcanic/plutonic arcs, such as those in the South American Andes, as well as collision of arcs or microcontinents with the main continental margin, and/or episodic extensional (rifting) events. Formation of base and precious metal mineral deposits in such settings is also very complex; however, a better understanding of the nature and controls on formation of deposits in these settings will greatly enhance our ability to explore for and find new mineral resources. I am investigating a variety of styles of continental margins and associated mineral deposits, including continental ("Andean-type") magmatic arcs, relatively juvenile arc settings that formed immediately adjacent to the edges of continents, and "orogenic" gold deposits formed in both post-collisional settings, and within accretionary prisms during subduction of spreading ridges. I am carrying out parallel studies of each of these settings in the Canadian Cordillera of BC and Yukon and in other, similar settings in Mexico, New Zealand and Australia. The goal of this research is to develop new insights into the nature of tectonism and formation of mineral deposits in continental margin settings from international studies and then apply that new knowledge to better understanding the tectonic evolution of the Canadian Cordillera and the processes that led to formation of mineral deposits.
我的研究重点是构造作用和沿大陆活动边缘形成的矿床之间的相互作用。大陆边缘是复杂的地质构造,通常是各种构造过程的发生地,包括海洋地壳的俯冲和由此产生的火山/深成弧的发展,例如南美洲安第斯山脉的火山/深成弧,以及弧或微大陆与主大陆边缘的碰撞,和/或幕式伸展(裂谷)事件。在这种环境下,贱金属和贵金属矿床的形成也非常复杂;然而,更好地了解这些环境中矿床形成的性质和控制因素将大大提高我们勘探和发现新矿产资源的能力。我正在研究各种类型的大陆边缘和相关的矿床,包括大陆(“安第斯型”)岩浆弧,在大陆边缘附近形成的相对年轻的弧环境,以及在碰撞后环境中形成的“造山带”金矿,以及在扩张脊的俯冲过程中形成的增生棱柱。我正在对加拿大BC省和育空地区的科迪勒拉地区以及墨西哥、新西兰和澳大利亚的其他类似地区进行平行研究。这项研究的目标是从国际研究中对大陆边缘构造和矿床形成的本质有新的认识,然后应用这些新知识来更好地理解加拿大科迪勒拉的构造演化和导致矿床形成的过程。
