Abstract

In this paper, we present a procedure for high pressure resin impregnation of microporous rock. This procedure produces the high- quality pore casts that reveal the fine details of the complex pore space of micritic carbonates. We carefully test our resin impregnation procedure and demonstrate that it renders the high resolution, 3D confocal images of pore casts. In our work, we use silicon micromodels as a reference to validate the key parameters of high-pressure resin impregnation. We demonstrate possible artifacts and defects that might develop during rock impregnation with resin, e.g., the resin shrinkage and gas trapping. The main outcome of this paper is a robust protocol for obtaining the high-quality epoxy pore casts suitable for rock imaging with Confocal Laser Scanning Microscopy (CLSM). We have implemented this protocol and provided the high resolution, three-dimensional (3D) imagery and description of microporosity in micritic carbonates.
高压树脂浸渍技术用于地质样品高分辨率共聚焦成像的验证
本文提出了一种微孔岩石高压树脂浸渍的方法。这一过程产生了高质量的孔型,揭示了泥晶碳酸盐复杂孔隙空间的精细细节。我们仔细地测试了我们的树脂浸渍程序,并证明它可以呈现高分辨率的孔铸型3D共聚焦图像。在我们的工作中,我们以硅微模型为参考,验证了高压树脂浸渍的关键参数。我们展示了树脂浸渍岩石过程中可能产生的工件和缺陷,例如树脂收缩和气体捕获。本文的主要成果是一个可靠的方案,以获得高质量的环氧树脂孔铸件适用于共聚焦激光扫描显微镜(CLSM)的岩石成像。我们已经实施了该方案,并提供了泥晶碳酸盐微孔隙度的高分辨率,三维(3D)图像和描述。
