97-06432 Axen One of the larger outstanding issues in plate tectonics concerns the initiation and evolution of continental rifting. A second important problem relates to the understanding of the evolution of transform faulting to strongly oblique rifting. The Gulf of Baja is the obvious natural laboratory for studying these problems because it is in the early stages of its evolution, it is well exposed, and it is accessible. Axen's study will contribute to our knowledge by providing an integrative data set including geological mapping, structural geology, and sedimentology, all supported by geochronologic work. By studying both the volcanic and the sedimentary rocks, as well as their structures and temporal relations, Axen's data will bear directly on the detailed geologic history of the evolution of the northern part of the Gulf of Baja.

板块构造学中最突出的问题之一是大陆裂陷的发生和演化。第二个重要问题涉及到对转换断裂向强斜裂陷演化的认识。巴哈湾显然是研究这些问题的天然实验室，因为它处于演化的早期阶段，它暴露得很好，而且很容易进入。Axen的研究将通过提供包括地质制图、构造地质学和沉积学在内的综合数据集，为我们的知识做出贡献，这些数据集都有地质年代学工作的支持。通过研究火山和沉积岩，以及它们的结构和时间关系，Axen的数据将直接与巴哈湾北部详细的地质历史演化有关。
