摘要
在最近发表在《地球动力学杂志》(Journal of Geodynamics, vol. 137, June 2020, 101733)上的一篇论文中,Fonseca et al.(2020)提出了一个发人深省的模型,旨在阐明泥盆纪和白垩纪之间新元古代Brasília褶皱带(BFB)的发掘历史。Fonseca等人(2020)完全基于文献信息和新的热年代学数据,提出了另一种模型,试图将构造隆升、侵蚀和来自BFB的碎屑物质流入克拉通内巴拉盆地结合起来。虽然这是一个受欢迎的建议和可靠的分析数据质量,但提出的假设与以前发表的一些作品不同。根据目前的磷灰石裂变径迹年龄,我们不同意他们的古地理模型,即Brasília褶皱带是泥盆纪至二叠纪期间帕拉那盆地碎屑岩的主要来源。我们评论的主要目的是澄清帕拉那盆地复杂的源-汇系统的现状。其次,我们试图证明为什么Fonseca等人(2020)提出的模型存在一些地球动力学和解释性问题,并且没有充分描述泥盆纪至二叠纪之间冈瓦纳西南部的古地理情景。
Comments on “Devonian to Permian post-orogenic denudation of the Brasília Belt of West Gondwana: Insights from apatite fission track thermochronology” by Fonseca et al. (2020)
In a recent paper published in the Journal of Geodynamics (vol. 137, June 2020, 101733), Fonseca et al. (2020) proposed a thought-provoking model aiming to elucidate the exhumation history of the Neoproterozoic Brasília Fold Belt (BFB) between the Devonian and Cretaceous periods. Exclusively based on information from the literature and new thermochronological data, Fonseca et al. (2020) presented an alternative model that tries to bind tectonic uplift, erosion, and the influx of clastic material coming from the BFB into the intracratonic Paraná Basin. Although the welcome proposal and reliable quality of the analytical data, the hypothesis presented diverges from several previously published works. In the light of the presented apatite fission-track ages, we disagree with their paleogeographical model, which puts the Brasília Fold Belt as a major source for clastic detritus to the Paraná Basin between the Devonian to Permian. The primary goal of our comments is to clarify the state-of-art of the intricate source-to-sink system of the Paraná Basin. Secondarily, we try to demonstrate why the model proposed by Fonseca et al. (2020) presents some geodynamic and interpretative problems and do not characterize an adequate paleogeographic scenario for southwest Gondwana between the Devonian to Permian periods.
