“金银双塔”为两根并排生长的石笋，石笋基底相连，最小间距不足1m，两根石笋高度均为35m，直径为2m。由滴水和飞溅水综合作用形成的“棕榈片”多向斜上方生长，平均延展长度为0.7m，平均厚度为0.2m，石笋体形高大且美观，是敢沫岩棕榈状石笋的典型代表。

Gold and silver twin towers are two stalagmites growing abreast, with their bases connected, and their minimum spacing is less than 1 m. Both of stalagmites are about 35 m high and 2 m in diameter. The "palm laminae" formed by the combination of dripping water and splashing water grew at an oblique angle with an average extension length of 0.7 m and an average thickness of 0.2 m. The stalagmite is tall and beautiful, and is a typical representative of the palm-shaped stalagmites in Ganmoyan.
