The Gallium/Aluminum Ratio in Rivers: A Possible New Tool inStudies of Weathering and Aluminum Geochemistry

人们对铝的地球化学很感兴趣 因为这种主要的土元素扮演着各种各样的角色 在风化过程中，在土壤化学中， 化学. 镓是一种具有地球化学性质的元素， 化学性质类似于铝。 因此，镓可能 作为铝的类似物。 考虑到现有的 关于镓的知识表明， 它的化学性质和铝的化学性质之间 河流中溶解的镓/铝比例的变化。 这 变化可以提供有关风化的有用信息 过程和铝地球化学。 有限的初步数据 这表明镓/铝比率确实发生变化。 因此，我们建议对 镓在河流中的行为

There is considerable interest in the geochemistry of aluminum because of the various roles that this major earth element plays in the weathering process, in soil chemistry, and in stream chemistry. Gallium is an element with a geochemistry and solution chemistry similar to that of aluminum. Thus, gallium might serve as an analogue for aluminum. A consideration of the available knowledge about gallium suggests that the slight differences between its chemistry and that of aluminum should lead to variations in the dissolved gallium/aluminum ratio in rivers. This variation may provide useful information regarding weathering processes and aluminum geochemistry. Limited preliminary data indicate that variations in the gallium/aluminum ratio do occur. We therefore propose a more thorough preliminary study of the behavior of gallium in rivers.
