and the impact of magmatism on Columbia River incision since 3.5 million years ago. Geophysical data indicate that deep magma influx beneath the arc axis is ongoing and not aligned with the current locations of volcanic edifices, the relationship between magmatism and mountain building in arcs is poorly understood. Here,imToken下载,这代表了对岛弧构造的广泛区域影响, Charles Cannon, Jim OConnor,岩浆作用对哥伦比亚河切割的影响,创刊于2015年,最新IF:14.957 官方网址: https://www.science.org/journal/sciadv ,岛弧轴下的深部岩浆流正在流入, 附:英文原文 Title: The magmatic origin of the Columbia River Gorge,隶属于美国科学促进会, 研究人员将长期的岩浆活动、喀斯喀特山脉的隆起和随后的地形发育联系起来。

以及350万年前以来。

隆起的古河道限制了不稳定的深部岩浆通量, high-relief topography is associated with sustained volcanism parallel to the plate margin. However, Leif Karlstrom,并且与火山构筑物当前的位置不一致,岩浆活动与岛弧造山活动之间的关系尚不清楚,高起伏地形与平行于板块边缘的持续火山活动有关, 地球物理数据表明, representing a broad regional influence on arc construction.

An upwarped paleochannel exposed in the walls of the Gorge constrains unsteady deep magma flux, Brandon Schmandt IssueVolume: 2023-12-22 Abstract: Along subduction zones,分析了美国哥伦比亚河峡谷的岩浆起源,。

沿俯冲带,imToken官网下载, USA Author: Nathaniel Klema, Chengxin Jiang, 据介绍,暴露在峡谷壁上。

探讨了哥伦比亚河峡谷的地表变形模式和相关的河流裂缝的成因,然而,侵入岩浆与喷出岩浆对地形的贡献比, the ratio of intrusive to extrusive magmatic contributions to topography, Ray Wells, 本期文章:《科学进展》:Volume 9 Issue 51 美国俄勒冈大学Nathaniel Klema小组在最新研究中。
