Hóa học ion chính, δ13C và 87Sr/86Sr như những chỉ thị về sự phát triển thủy hóa và nguồn gốc của độ mặn trong nước ngầm ở lưu vực Yuncheng, Trung Quốc
Tóm tắt
Các quá trình kiểm soát hóa học thủy văn trong lưu vực Yuncheng, Trung Quốc, đã được phân tích bằng cách sử dụng hóa học ion chính, tỷ lệ 87Sr/86Sr và giá trị δ13C. Quá trình bay hơi nước trong giai đoạn nạp nước đã làm tăng nồng độ chất tan lên khoảng 5–50 lần trong các tầng nước cổ sâu, trong khi mức độ bay hơi cao hơn đã xảy ra trong các tầng nước ngầm hiện đại nông. Các trầm tích tầng chứa nước (bột vàng) chứa khoảng 15% trọng lượng canxit; xu hướng trong nồng độ HCO3 của nước ngầm và giá trị δ13C (dao động từ −16.4 đến −8.2‰) cho thấy quá trình phong hóa cacbonat là một nguồn DIC quan trọng. Tỷ lệ 87Sr/86Sr của nước ngầm (0.7110–0.7162, trung vị 0.7116) tương tự như ở cả carbonate bột vàng (0.7109–0.7116) và nước mưa địa phương (0.7112), và thấp hơn đáng kể so với Sr trong silicat tầng chứa nước (0.7184–0.7251). Mặc dù có bằng chứng cho sự hòa tan đáng kể của cacbonat, nước ngầm chủ yếu nghèo Ca (< 10% tổng số cation) và giàu Na, do quá trình trao đổi cation. Sự bão hòa với các khoáng chất cacbonat xảy ra trong hoặc ngay sau giai đoạn nạp nước (tất cả các chỉ số bão hòa canxit và dolomit đều dương). Quá trình hòa tan cacbonat tiếp theo trong tầng chứa nước sâu phải diễn ra như một quá trình thứ hai, để đáp ứng với sự mất Ca (qua trao đổi ion) và/hoặc thông qua sự hòa tan không đồng nhất của dolomit và canxit không tinh khiết. Điều này nhất quán với các tương quan dương giữa các giá trị δ13C và tỷ lệ Mg/Ca cũng như Sr/Ca (r² = 0.32 và 0.34).
