FIRE (The Finnish Reflection Experiment) profile 3 including part 3A

The Finnish Reflection Experiment (FIRE) dataset consists of seismic reflection data from 2,104 km of common mid-point (CMP) lines. The four FIRE transects cross-cut several geologically and economically important features of Fennoscandian Shield such as the Archaean–Proterozoic boundary and Outokumpu ore district.

The original FIRE project took place between 2001 and 2005. It was conducted in co-operation between the Geological Survey of Finland (GTK), the Institute of Seismology at the University of Helsinki and the Institute of Geosciences and the Sodankylä Geophysical Observatory of the University of Oulu. The seismic contractor in the FIRE project was Specgeofizika S.E. together with Machinoexport S.E.

The original report of the FIRE project can be found in the Special Paper 43 of the Geological Survey of Finland:

This dataset covers the FIRE profile 3 including additional part 3A. Data consist of pole co­ordin­ate files, common mid-point coordinate files, original field recordings, shot gathers, field statics, normal move-out and dip move-out stacks, migrated and depth-converted stacks, envelope sections and variable-area plots.

芬兰反射实验（Finnish Reflection Experiment, FIRE）数据集包含总长2104千米的共中心点（common mid-point, CMP）测线的地震反射数据。四条FIRE测线横穿芬诺斯坎迪亚地盾（Fennoscandian Shield）多处兼具重要地质与经济价值的构造，包括太古宙-元古宙界线与奥蒂昆普（Outokumpu）矿区。

原始FIRE项目实施于2001年至2005年，由芬兰地质调查局（Geological Survey of Finland, GTK）、赫尔辛基大学地震学研究所、奥卢大学地球科学研究所与索丹屈拉地球物理天文台联合开展。FIRE项目的地震勘探承包商为Specgeofizika S.E.与Machinoexport S.E.两家单位。
