Hello

total budget of the research paper is – 30&-50$ max for both papers

i want 2 research papers for publish . one in GEOLOGY and another in environment science . I have no idea about the topics but some topics i can suggest you like:-

In geology:-
1.Seismology
Source processes of earthquakes and aseismic slip events along plate boundaries. Evolution of fault strength coupled with pore fluid pressure. Earthquake source parameter studies including radiated seismic energy and energy partitioning, and the source properties of non-volcanic tremor and triggered earthquakes.

Volcanology
Petrology and geochemistry of intermediate and felsic magmas. Understanding physical processes and forecasting eruptions at active subduction-zone volcanoes. Geochemistry of volcanic gases, their use for eruption prediction, and their impact on the atmosphere.

Sedimentary Geology and Isotopic Geochemistry
Sedimentology, stratigraphy, and isotope geochemistry as guides to reconstructing ancient environments. Reconstruction of paleoenvironmental change during the Neoproterozoic to early Phanerozoic. Relationships between between tectonics (i.e. supercontinental break-up and assembly), seawater chemistry and ocean redox, severe climatic fluctuations (including snowball Earth), and the origin and diversification of animals. Recovery of the geochemical memory of large-scale Earth system processes (e.g., microbial control of the global S cycle; anthropogenic manipulation of atmospheric OH abundances). Investigations of microbial biogeochemistry under an anoxic Archean atmosphere, to constrain mass fluxes in the Phanerozoic geologic sulfur cycle, and to track processes that control the pollution-cleansing oxidants (OH, O3) in the modern atmosphere.

Mineralogy
Chemistry and crystallography of carbonate minerals. Experimental investigations of the effect of environmental factors (e.g., solution composition and temperature) on the morphology and composition of calcite.
