Data of Self-Weight Consolidation Process of Water-Saturated Deltas on Mars and Earth

Data of the paper "Self-Weight Consolidation Process of Water-Saturated Deltas on Mars and Earth". This dataset includes five tables. Table S1 is the original data of the measurements of the moisture content w0, Table S2 is the original data of the pycnometer test, which was conducted to obtain the specific gravity Gs of our samples, Table S3 is the original data of the consolidation experiments, Table S4 is the original data of the permeability experiments, and Table S5 is the martian global delta relief obtained by us based on MOLA data, which is used as the maximum thickness of a delta.

Table S1. The original data of the measurements of the moisture content w0. The initial void ratio is calculated by equation (1).  A' is the inner area of the consolidation container.

Table S2. The original data of the pycnometer test, which was conducted to obtain the specific gravity Gs of our samples. The specific gravity Gs can be derived from mdGwT /(mbw+md+mbws), where md is the samples’ dry mass, mbw is the total mass of the pycnometer and water, mbws is the total mass of the pycnometer, water and samples, and GwT is the specific gravity of pure water at T ℃.

Table S3. The original data of consolidation experiments of our samples. The void ratio is calculated by equation (2).

Table S4. The original data of permeability experiments of our samples. The hydraulic conductivity K was calculated by equations (3) and (4). The inner area of the consolidation container is 30 cm2, the cross-sectional area a' of the water pipe is 0.89286 cm2, and the seepage path length L equals the sample initial height h0 minus the accumulated height ΣΔhi. t1 and t2 are the first and the second test results of time-taken for water dropping from H1 to H2, respectively. t is the average of t1 and t2. T’ is the temperature during the experiments. Note: we only test the T’ of the third group and here we used the average of T’ (=12.5℃) to represent the temperature of all three parallel groups during the experiments. It’s acceptable because T’ varies slightly throughout the experiments, whose fluctuations hardly affect the order of magnitude of the hydraulic conductivity K. The seepage velocity v=Q/A’t, in which Q is the volume of water that seeps out of the samples.

Table S5. The delta relief of a delta. The locations of martian deltas are based on the database of Wilson et al. (2021)
