Dear Colleagues,
In geology, cross-scale cracks are essential for understanding the mechanical behavior of rocks. They affect the permeability and porosity of rocks and therefore influence fluid flow, such as groundwater movement and hydrocarbon reservoirs. Meanwhile, they play a crucial role in the fragmentation of rocks during natural processes like erosion, weathering, and faulting. In civil and mining engineering, knowledge of cross-scale cracks is vital for assessing the stability of rock masses in construction projects, tunnels, and mining operations. The presence of these cracks can significantly impact the strength and deformation characteristics of rocks, which can have safety and economic implications. Cross-scale cracks in rocks often interact with various environmental factors, including the presence of different phases (such as air, water, and minerals) and multiple physical fields (such as stress, temperature, and humidity). Understanding how these cracks respond to multi-phase and multi-field coupling actions is important for predicting rock behavior under diverse conditions. In recent years, many scientists and engineers have used various techniques to study cross-scale cracks in rocks, including imaging methods like scanning electron microscopy (SEM), X-ray computed tomography (CT), and acoustic emission monitoring. These tools allow researchers to observe and analyze the characteristics of cracks at different scales.
This Special Issue aims to gather cutting-edge research and recent advances concerning the formation and evolution of cross-scale cracks within rock masses, and to promote their practical implications in fields like geotechnical engineering, reservoir engineering, and hazard assessment. Both original research papers and review articles are welcome.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
