摘　　要：21世纪的花岗岩怎样研究是一个需要探索的问题。作者认为,应当对现有的花岗岩理论、流行的说法以及术语等进行清理和反思,汲取其精华,剔除其糟粕,抛弃那些不科学、不符合实际、不符合逻辑的部分。例如,在花岗岩研究中摈弃结晶分离的理论,缩小花岗岩混合作用的意义,限制花岗岩构造环境理论的应用,取消幔源、壳源和壳幔混合源的术语等。作者指出,今后花岗岩研究应当着重解决两个问题:(1)花岗岩是怎样的?(2)它何以是这样的?文中提出5个方面的任务作为今后研究的重点,即:开展花岗岩立典式的研究,将花岗岩研究与古老地壳的研究结合起来,将花岗岩物理性质研究与地球化学究结合起来,开展广泛的实验岩石学研究和创建新的"大陆构造学"理论。鉴于花岗岩研究目前存在的严重误区,现有的花岗岩理论几乎全面崩溃,由四大基石支撑的花岗岩大厦行将坍塌,花岗岩研究正面临全球大洗牌。为此,作者建议开展一场关于花岗岩的大辩论,目的是清理思路,认清问题,明确方向,找到出路。作者呼吁,我们应当加强学习,加速引进人才,克服急躁情绪和浮夸的学风,摈弃从众思想和奴性思想,不以SCI论英雄,改进我们的学习,改善我们的制度,以推进花岗岩研究迈上新台阶。How to study granite in the 21^st century is still a problem. The authors hold that the current theory for granite study and the popular parlance and terms should be checked up and reflected. Furthermore, we should absorb the essence, reject the dross and abandon those which are unscientific, unrealistic and unreasonable. For example, we should discard the theory of fractional crystallization, lessen the significance of mixing of granite, restrict the application of the theory of tectonic environment and cancel the terms such as mantle-derived, crust-derived and mixed crust-mantle-derived in the study of granite. The authors propose two main questions to be solved in the future research on granite ： （ 1 ） what is granite？ （ 2 ） why is it like this？ This paper puts forward the following five aspects as the key points for the future work ： （ 1 ） to carry out case study for typical granite ; （2） to combine the research of granite with that for the ancient crust; （3） to combine the research of physical character of granite with geochemistry of granite; （4） to carry out comprehensive research on experimental work; and （5） to establish new theory of ＂Continental Tectonics＂. Due to the severe problems existing in current granite research, current theory of granite nearly fall apart, the mansion of granite braced by four footstones is about to collapse. Therefore, the authors suggest a debate should he held for granite study, aiming to clear up thoughts, to recognize problems, to define the direction and to find a way out. The authors advocate to advance the study of granite by strengthening learning, quickening the pace of introducing talents, overcoming the emotion of impatience and boasting and exaggeration in the style of learning and abandoning herd and slavish thought. We should further stop evaluating individuals by SCI and improve related policy.
