Nguồn gốc của các chuỗi hố trong lòng các miệng núi lửa Copernican trên mặt trăng
Tóm tắt
Có những chuỗi hố nhỏ trong lòng các miệng núi lửa Copernican trên mặt trăng. Chúng thường có quy mô rất nhỏ đến mức ít tàu vũ trụ trên mặt trăng có thể phát hiện được hình thái chi tiết của chúng. Bằng cách kết hợp dữ liệu từ camera của các nhiệm vụ Lunar Orbiter, Lunar Reconnaissance Orbiter (LRO), Kaguya và Chang’e-1, 5 miệng núi lửa Copernican lớn đại diện ở các địa hình khác nhau trên bề mặt mặt trăng được lựa chọn để nghiên cứu nguồn gốc của các chuỗi hố trong lòng miệng núi lửa. Hình thái và đặc điểm phân bố của các chuỗi hố được tham chiếu bằng các hình ảnh độ phân giải cao trong nghiên cứu này. Nghiên cứu cho thấy rằng chính các hoạt động magma từ lớp magma nằm dưới bề mặt kết hợp với sự tồn tại của các võng và đứt gãy dưới lòng miệng núi lửa đã dẫn đến sự hình thành của các chuỗi hố này. Mô hình này được xác minh và thảo luận thêm bằng cách sử dụng dữ liệu độ dày lớp đất sét trong lòng miệng núi lửa. Mô hình của chúng tôi gợi ý rằng các chuỗi hố vẫn đang phát triển trong lòng các miệng núi lửa Copernican và mặt trăng có thể chưa hoàn toàn lạnh lẽo. Cuối cùng, các giới hạn của mô hình và công việc tương lai tiềm năng được thảo luận dựa trên các dữ liệu hiện có.
