The large or small scale of a landslide is natural, widespread process, resulting from the downward and outward movement slope-forming materials, such as sculpting landscape. Characterized material properties’ inhomogeneities conditions become challenge process required availability wide range data, observations, measurements with an evaluation geological hydrological conditions. Detailed investigations represent essential component risk mitigation relying on subsurface investigations,...

This study on the sedimentological and reservoir petrophysical properties (porosity, permeability, density, sonic velocity) of sandstones were conducted sedimentary rocks belonging to Miri Formation (Middle Miocene) from Nyalau Bintulu in Sarawak. The objectives are i) investigate determine facies characteristics different types sandstones, ii) establish relationships between properties. Two lithofacies have been sampled outcrops four based lithology, structures, fossil traces bed geometry....

Ground penetrating radar (GPR) are non-invasive geophysical techniques that enhance studies of the shallow subsurface. The purposes this work to study subsurface composition Balik Pulau area in Penang Island and identify geology features. Data acquisition for GPR is by using 250 MHz antenna cover 200m survey line at Jalan Tun Sardon, Pulau. was divided into ten sections 20 m each. Results from shows there low EM reflection along first 40 line. Intense reflections were recorded distance 100...

This paper presents the multiple linear regression (MLR) models developed from electrical resistivity and seismic refraction surveys for quick prediction of subsurface soil’s shear strength parameters. A total four parameters have been considered with velocity as independent variables: soil cohesion internal friction angle dependent variables. In order to mitigate effects nonlinearity velocity, both datasets were initially log-transformed conform fundamental assumptions analysis. Two...

Outcrop studies are a fascinating part of geology as it evidently shows the aftermath how earth forming processes billion years ago. Outcrops do not cover majority Earth's land surface is covered by soils or vegetation thus cannot be seen clearly. In Kedah, Malaysia, there many outcrops exposed in state. The aim this research was to correlate parameters geophysical survey with properties Permian facies Semanggol Formation Kedah. consists bedded chert and claystone. Two technique, electrical...

Both natural and anthropogenic coastal landforms characterize Penang Island. As years have passed it is a challenge to differentiate the genuineness of landmasses created by geological formations or reclamation projects. An account given environmental impact solid wastes used for reclaiming land in areas major sewage outfall western channel. Leaching heavy metals was shown be one main sources contamination from wastes. This paper presents eight lines ground penetrating radar (GPR) surveys...

The role of geophysics in Environmental Earth Sciences and Engineering is considered. In the developing era, has mainly contributed investigation new constructions such as tunnels, road, dams high-rise buildings. This study was carried out to assess foundation depths around a construction site Southern Industrial & Logistics Clusters (SiLC), Nusajaya, Johor using 2-D resistivity method. method with view characterize different subsurface geological provide engineering environmental...

Mudrock is a type of sedimentary rock whose original constituents are clays and muds. Mudrocks fine grained siliciclastic which include mudstone claystone depending on the grain size. The colour function its minerology content geochemistry processes. One common structure mudrocks lamination due to variations in size composition changes. importance as mixture for cement produce brick used building structure. This research emphasizes resistivity value mudrocks; exist northwestern Peninsula...

<title>Abstract</title> Magnetotellurics (MT) method utilizes lightning activities and solar wind interactions as electromagnetic sources in measuring resistivity distribution to great depths. Static shift is a common problem MT where actual data shifted higher or lower logarithmic scale but maintains the same apparent (ρA) curve. Currently, static corrected using vertical electrical sounding (VES) transient (TEM) data, which give ρA 1D that does not depicts subsurface materials precisely....

Abstract Fischer plots find extensive applications in paleoenvironmental studies as visual depictions of sea and lake-level fluctuations. They graphically represent the linearly adjusted alterations cumulative thickness sedimentary cycles a specific geographical region over time, with respect to either cycle number or depth strata. The observed successive intervals sediment deposition erosion, that are driven by fluctuations rates subsidence level. Previous researchers have introduced...

Abstract The ongoing investigation into the microfacies and diagenesis of Setul limestone reveals a considerable expanse formation that remains relatively unexplored. comprehension diagenetic processes within sedimentary rocks holds paramount significance in predicting their viability as hydrocarbon reservoirs, decoding geological history depositional environment given region, reconstructing past climatic conditions, understanding fossil record. To meet stipulated research objectives, which...

The parameters of seismic refraction and electrical resistivity play a crucial role in geological studies, as they provide insights into the composition rocks or soil beneath Earth’s surface. Previous researchers have established reference ranges for velocity values based on different rock types, which are presented tabulated forms. However, wide variability these sometimes leads to challenges interpretation due overlapping ranges. In region Perlis, Malaysia, comprehensive geophysical...

Sandstones are very important as reservoirs for oil and gas; more than 50% of the world’s petroleum reserve is estimated to occur in sandstones. Depositional environments, thus facies characteristics, determine overall reservoir properties The purpose studying sedimentological characteristics petrophysical Tertiary quality sandstones from Sabah Sarawak investigate relationships between different types

The study location was at Bukit Kukus, Kuala Ketil, Kedah, Malaysia where the geological outcrop of this Semanggol Formation comprises chert, mudstone, and volcanic tuff. conducted using two geophysical methods, which are 2-D Resistivity Ground Penetrating Radar (GPR). objectives to correlate both methods through value conductivity identify physical properties rocks porosity permeability. data acquisition for on same line. For method, length line is 60 m with 1.5 electrode spacing array used...

Abstract Geophysical approaches are used for site characterization to determine the dynamic behaviour of soil. Structures built on a without sufficient assessment prone collapse or failure. Thus, before beginning any building activity, it is critical assess soil qualities. This significant because buildings constructed top ground surface, supported by underlying and rock. work aimed competent layer foundations. study was conducted evaluate Paya Terubong Penang Island. Resistivity, Young's...

Rock is a naturally occurring substance. The study of rock properties and its mineral composition have many useful information benefits, such as for building construction aggregates. Understanding how material was formed will reveal it can be used in building, limitations weathered over time. research objectives are to categorize the based from methods geophysics, geotechnical petrography analysis, identify possibility purpose. location at Bukit Chondong, Beseri, Perlis, Malaysia. conducted...

The objective of this study is to determine the structure and condition subsurface by using 2D resistivity Ground Penetrating Radar (GPR) methods. was conducted at SK Sungai Batu, Teluk Kumbar, Penang Island.
